Stone by Stone

I have a wall you cannot see
Because it’s deep inside of me
It blocks my heart on every side
And helps emotions there to hide
You can’t reach in
I can’t reach out
You wonder what it’s all about
The wall I built that you can’t see
Results from insecurity
Each time my tender heart was hurt
The scars within grew worse and worse
So stone by stone
I built a wall
That’s now so thick it will not fall
Please understand that its not you
Continue trying to break through
I want show much to show myself
And love from you will really help
So bit by bit
Chip at my wall
Til stone by stone, it starts to fall
I know the process will be slow
It’s never easy to let go
Of hurts and failures long in grounded
Upon ones heart from years of pain
I’m so afraid
To let you in
I know I might get hurt again
I try so hard to break the wall
But I seem to get nowhere at all
For stone upon each stone ive attacked
And left between them not a crack
The only way
To make it fall is in imperfections in the wall
I did the best I could to build
A perfect wall but there are still
A few small flaws which are the key
To breaking through the wall to me
Please use each flaw
To cause a crack
To knock a stone off of the stack
For just as stone by stone was laid
With every hurt and every pain
So stone by stone the wall will break
As love replaces every ache
Please be the one who cares enough
To find the flaws no matter what.

What About Love?

We think about it,
sing about it,
dream about it,
and lose sleep worrying about it.

When we don't have it,
we search for it;
when we discover it,
we don't know what to do without it,
when we have it,
we fear losing it.

It's a constant source of pleasure and pain
but we can't predict from one minute to the next,
which could be today.

We love our parents,
our brothers and sisters,
our boyfriends and girlfriends,
our cats and dogs,
our comfortable shoes
and our baseball gloves.

Love
- It's a short work,
easy to spell,
difficult to defind,
impossible to live without.

My Angel

The scarred and broken heart of mine
Was healed sweetly by her gentle smile
All the chaos in my life
Was silenced by her bluesy eyes

Her lips are like that of an angel
So beautiful, so red
That if i die of inhumanity
They would wake me up from dead

The words she speaks
Come out like song from heaven
Like symphonic melodies
As holy as number seven

The smile from her face
Just blinds my eyes
It has just become harder day by day
To say to her goodbye

When I Met You

Many times I’ve had my heart broken into pieces.
Making me live a life of mess.
Many times I’ve loved to the fullest,
But still end up crying like the rest.


Then one day you came into my world...
You comforted me with love every time I feel cold.
And with you is where I want to be with till we grow old..
Making our love as the greatest story ever told.


Never thought I’d fall so deep.
Feels like I just woke up from a long sleep.
Never thought I could still be this happy..
Now seeing the world smiling back at me.


You are my love of a lifetime,
And if loving you is a crime,
Then I’m definitely guilty
For loving you with all of me.


I LOVE YOU, JOY, till eternity.

The Water Cycle

Water on Earth is always changing. Its repeating changes make a cycle. As water goes through its cycle, it can be a solid (ice), a liquid (water), or a gas (water vapor). Ice can change to become water or water vapor. Water can change to become ice or water vapor. Water vapor can change to become ice or water.
How do these changes happen? Adding or subtracting heat makes the cycle work. If heat is added to ice, it melts. If heat is added to water, it evaporates. Evaporation turns liquid water into a gas called water vapor.
If heat is taken away from water vapor, it condenses. Condensation turns water vapor into a liquid. If heat is taken away from liquid water, it freezes to become ice.
The water cycle is called the hydrologic cycle. In the hydrologic cycle, water from oceans, lakes, swamps, rivers, plants, and even you, can turn into water vapor. Water vapor condenses into millions of tiny droplets that form clouds. Clouds lose their water as rain or snow, which is called precipitation. Precipitation is either absorbed into the ground or runs off into rivers. Water that was absorbed into the ground is taken up by plants. Plants lose water from their surfaces as vapor back into the atmosphere. Water that runs off into rivers flows into ponds, lakes, or oceans where it evaporates back into the atmosphere.
The cycle continues.

Human Inputs to the Phosphorus Cycle:
Human influences on the phosphate cycle come mainly from the introduction and use of commercial synthetic fertilizers. The phosphate is obtained through mining of certain deposits of calcium phosphate called apatite. Huge quantities of sulfuric acid are used in the conversion of the phosphate rock into a fertilizer product called "super phosphate".
 
Plants may not be able to utilize all of the phosphate fertilizer applied, as a consequence, much of it is lost form the land through the water run-off. The phosphate in the water is eventually precipitated as sediments at the bottom of the body of water. In certain lakes and ponds this may be redissolved and recyled as a problem nutrient.
 
Animal wastes or manure may also be applied to the land as fertilizer. If misapplied on frozen ground during the winter, much of it may lost as run-off during the spring thaw. In certain area very large feed lots of animals, may result in excessive run-off of phosphate and nitrate into streams.
 
Other human sources of phosphate are in the out flows from municipal sewage treatment plants. Without an expensive tertiary treatment, the phosphate in sewage is not removed during various treatment operations. Again an extra amount of phosphate enters the water.

The Water Cycle

Run and get a glass of water and put it on the table next to you.  Take a good long look at the water.  Now -- can you guess how old it is?  
    
The water in your glass may have fallen from the sky as rain just last week, but the water itself has been around pretty much as long as the earth has!   When the first fish crawled out of the ocean onto the land, your glass of water was part of that ocean.  When the Brontosaurus walked through lakes feeding on  plants, your glass of water was part of those lakes.  When kings and princesses, knights and squires took a drink from their wells, your glass of water was part of those wells.
And you thought your parents were OLD

The earth has a limited amount of water.  That water keeps going around and around and around and around and (well, you get the idea) in what we call the "Water Cycle". This cycle is made up of a few main parts:
  • evaporation (and transpiration)
  • condensation
  • precipitation
  • collection

Evaporation:   Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapor or steam. The water vapor or steam leaves the river, lake or ocean and goes into the air.
Do plants sweat?
Well, sort of.... people perspire (sweat) and plants transpire.  Transpiration is the process by which plants lose water out of their leaves.  Transpiration gives evaporation a bit of a hand in getting the water vapor back up into the air.

Condensation:    Water vapor in the air gets cold and changes back into liquid, forming clouds. This is called condensation.
You can see the same sort of thing at home... pour a glass of cold water on a hot day and watch what happens.  Water forms on the outside of the glass.  That water didn't somehow leak through the glass!  It actually came from the air.  Water vapor in the warm air, turns back into liquid when it touches the cold glass.

Precipitation:  Precipitation occurs when so much water has condensed that the air cannot hold it anymore.  The clouds get heavy and water falls back to the earth in the form of rain, hail, sleet or snow.

Collection:  When water falls back to earth as precipitation, it may fall back in the oceans, lakes or rivers or it may end up on land.  When it ends up on land, it will either soak into the earth and become part of the “ground water” that plants and animals use to drink or it may run over the soil and collect in the oceans, lakes or rivers where the cycle starts
all over again.

Carbon Cycle

The Carbon Cycle is a complex series of processes through which all of the carbon atoms in existence rotate. The same carbon atoms in your body today have been used in countless other molecules since time began. The wood burned just a few decades ago could have produced carbon dioxide which through photosynthesis became part of a plant. When you eat that plant, the same carbon from the wood which was burnt can become part of you. The carbon cycle is the great natural recycler of carbon atoms. Unfortunately, the extent of its importance is rarely stressed enough. Without the proper functioning of the carbon cycle, every aspect of life could be changed dramatically.
picture of carbon cycle We believe that it's vital to understand how the carbon cycle works in order to see the danger of it not working. Therefore, let's look at a sample carbon cycle and explore how carbon atoms move through our natural world. Plants, animals, and soil interact to make up the basic cycles of nature. In the carbon cycle, plants absorb carbon dioxide from the atmosphere and use it, combined with water they get from the soil, to make the substances they need for growth. The process of photosynthesis incorporates the carbon atoms from carbon dioxide into sugars. Animals, such as the rabbit pictured here, eat the plants and use the carbon to build their own tissues. Other animals, such as the fox, eat the rabbit and then use the carbon for their own needs. These animals return carbon dioxide into the air when they breathe, and when they die, since the carbon is returned to the soil during decomposition. The carbon atoms in soil may then be used in a new plant or small microorganisms. Ultimately, the same carbon atom can move through many organisms and even end in the same place where it began. Herein lies the fascination of the carbon cycle; the same atoms can be recycled for millennia!



Now that you have learned about the cycle, let's go into some specifics.

Nitrogen Cycle

The main component of the nitrogen cycle starts with the element nitrogen in the air. Two nitrogen oxides are found in the air as a result of interactions with oxygen. Nitrogen will only react with oxygen in the presence of high temperatures and pressures found near lightning bolts and in combustion reactions in power plants or internal combustion engines. Nitric oxide, NO, and nitrogen dioxide, NO2, are formed under these conditions. Eventually nitrogen dioxide may react with water in rain to form nitric acid, HNO3. The nitrates thus formed may be utilized by plants as a nutrient.
 
Nitrogen in the air becomes a part of biological matter mostly through the actions of bacteria and algae in a process known as nitrogen fixation. Legume plants such as clover, alfalfa, and soybeans form nodules on the roots where nitrogen fixing bacteria take nitrogen from the air and convert it into ammonia, NH3. The ammonia is further converted by other bacteria first into nitrite ions, NO2-, and then into nitrate ions, NO3-. Plants utilize the nitrate ions as a nutrient or fertilizer for growth. Nitrogen is incorporate in many amino acids which are further reacted to make proteins.
 
Ammonia is also made through a synthetic process called the Haber Process. Nitrogen and hydrogen are reacted under great pressure and temperature in the presence of a catalyst to make ammonia. Ammonia may be directly applied to farm fields as fertilizer. Ammonia may be further processed with oxygen to make nitric acid. The reaction of ammonia and nitric acid produces ammonium nitrate which may then be used as a fertilizer. Animal wastes when decomposed also return to the earth as nitrates.
 
To complete the cycle other bacteria in the soil carry out a process known as denitrification which converts nitrates back to nitrogen gas. A side product of this reaction is the production of a gas known as nitrous oxide, N2O. Nitrous oxide, also known as "laughing gas" - mild anesthetic, is also a greenhouse gas which contributes to global warming.

There's A Girl

The road I travel is working
off railroads and gravel,
Fixing ties and losing some time.
There’s a girl in Tulsa
that’s sweet on this fella,
She says that I am
always on her mind.
I should grab my backpack,
hop in my fastback
It’s only a short drive.
If I could reach her
I know I could teach her,
How sweet it is to be mine.
If only I could make up for lost time.
There’s a girl waiting when I have the time.
The rails have come to own me
and time is never on my side
work seems only to slow me
I'm here only for the lonely ride.
The road I travel is working
off back roads and gravel,
Fixing rails but I just keep
falling behind.
There’s a girl in Chama
that’s sweet on this fella,
She says I could easily
make her mine.
I should grab my backpack
hop in my fastback,
It’s only a short drive.
If I could reach her
I know I could teach her,
How easy it is to be mine.
But I just keep falling further behind.
There’s a girl waiting when I’m not behind.
The rails have come to own me
and time is never on my side
work seems only to slow me
I'm here only for the lonely ride.
The road I travel is working
off dirt roads and gravel,
Driving spikes to the end of this line.
There’s a girl in Mesa
that’s sweet on this fella,
She says I should call
and charge it to her dime.
I should grab my backpack
hop in my fastback,
It’s only a short drive.
If I could reach her
I know I could teach her,
How soon she could be mine.
But I can’t find the end of this line.
There’s a girl waiting at the end of this line.
The rails have come to own me
and time is never on my side
work seems only to slow me
I'm here only for the lonely ride.
God I hope there’s a girl still waiting at the end of this line.

The Carbon Cycle


All living things are made of carbon. Carbon is also a part of the ocean, air, and even rocks. Because the Earth is a dynamic place, carbon does not stay still. It is on the move!
In the atmosphere, carbon is attached to some oxygen in a gas called carbon dioxide.
Plants use carbon dioxide and sunlight to make their own food and grow. The carbon becomes part of the plant. Plants that die and are buried may turn into fossil fuels made of carbon like coal and oil over millions of years. When humans burn fossil fuels, most of the carbon quickly enters the atmosphere as carbon dioxide.
Carbon dioxide is a greenhouse gas and traps heat in the atmosphere. Without it and other greenhouse gases, Earth would be a frozen world. But humans have burned so much fuel that there is about 30% more carbon dioxide in the air today than there was about 150 years ago, and Earth is becoming a warmer place. In fact, ice cores show us that there is now more carbon dioxide in the atmosphere than there has been in the last 420,000 years.

For A Cute Girl

You changed my world with a blink of an eye
That is something that I can not deny
You put my soul from worst to best
That is why I treasure you my dearest Marites

You just don't know what you have done for me
You even pushed me to the best that I can be
You really are an angel sent from above
To take care of me and shower with love

When I'm with you I will not cry even a single a tear
And your touch have chased away all of my fear
You have given me a life that I could live worthwhile
It is even better everytime you smile

It so magical those things you've made
To bring back my faith that almost fade
Now my life is a dream come true
It all began when I was loved by you

Now I have found what I am looking for
It's you and your love and nothing more
Co'z you have given me this feeling of contentment
In my life something I've never felt

I wish I could talk 'til the end of day
But now I'm running out of things to say
So I'll end by the line you already know
"I LOVE YOU" more than what I could show

March 01, 2012

I Love U

What is it with Love?
That makes me then breaks me?
When in love do I truly love?
Is it really love Or do I think that I love?
Maybe I just love being in love
Or love the idea of being in love?
I spent my whole life chasing love.
In the end the one thing I truly love
Could just be the Meir pursuit of love

I have heard it said
True love comes around only once in life…
I never believed that until I met you.
I now know what true love means,
For never have I loved someone
as I love you…

Because our love is eternal
There's nothing left to say,
Except to say this one last word.
I love you more each day

Beauty


Some flowers bloom in fall you know,
At summers end their blossoms show
And as the rose’s beauty falls
The dream of love will haunt us all.
Jewelry, like a portraits frame
Enhances beauty just the same.
A work of art is best by far
That tells the viewer who they are
But just as what I say is true,
A frame cannot change the view.
It cannot show a beauty fair
Where beauty first, was never there.
It cannot change a scowling face
To one that’s fair and full of grace.
It cannot fix a heart that’s blue
Or make a heart forever true.
Their is that beauty of a kind
That knows no boundaries of time
The shining of a soul inside
That none can ever hope to hide.
What ever shall I say to thee
That touches love’s sweet rhapsody
To embrace with time and heart
A truly lovely peace of art.
There is that loyalty of spirit
That one feels whenever near it
That so enthralls the heart of man
And searches then to understand
There is more to life then beauty,
Their is honor, love and duty
As in the heart that it entails,
Beauty wears so many vales.

A Mask Of Beauty

A sheer smile skips those lips
How I want to hold your dearest mask
To think I am ashamed of thou beauty
Merely of adoration of each sensual amnesty
How fawn I am of your mask
To hide behind your beauty
I am the limp of a child that wonders with a thought
I put my hand on thee
And these hands want to know more
To close my eyes and dew soaks the stars
They shine no more
There beauty is diminished
I shall hide behind this mask as well
You will never be alone
Beauty has the eye of the beholder
Hold me dear love
And we shall look upon thy pupils
And we will make a stream of kisses
To beauty of wilderness we will create our own
To a world that is beauty
To a mask that shades underneath
A more over victory of passion over lust
A passion of beauty oh how I can taste it
Please fade with me from this world
And beauty will prevail
Through all the toils and snares
How I love you dearly
How my beauty shines for you
A red carpet for you to walk on
To follow
A love..
A beauty….
A dream….

Beautiful Memory


Today will be the past; come tomorrow
Why nothing or no one is above you
Today I will buy, steal, or borrow
So that the past reveals that I love you

I will yearn tomorrow for another today
Anything to strengthen our unity
The past is the map guiding the way
Every new day brings new opportunity

I will awaken knowing my primary goal
Accomplish something big or small
Fresh or increase something old
Deeds that will heighten our castle wall

I shall conduct myself in ways more than suitable
My gifts to the past will make memories beautiful

Tomorrow will deliver more affection and chivalry
I must today, make yesterday a beautiful memory

Yesterday will be the proof I was there
With facts that no one tried more
Applying layers of unwavering care
Flooding you with joy at the final score


It's ignited a passion that I have to vent
To stray from you; I cannot swallow
Necessary and a time well spent
Today will be the past; come tomorrow

Bright Star

Bright star, would I were steadfast as thou ar t-
Not in lone splendour hung aloft the night
And watching, with eternal lids apart,
Like nature's patient, sleepless Eremite,
The moving waters at their priestlike task
Of pure ablution round earth's human shores,
Or gazing on the new soft fallen mask
Of snow upon the mountains, and the moors -
No - yet still steadfast, still unchangeable,
Pillow'd upon my fair love's ripening breast,
To fed for ever its soft fall and swell,
Awake for ever in a sweet unrest,
Still, still to hear her tender-taken breath,
An so live ever-or else swoon to death.

Oxygen-Carbon Dioxide Cycle

The Carbon Dioxide- Oxygen Cycle relates to the relationship between Carbon Dioxide [CO2] breathing plants and Oxygen [O2] breathing lifeforms. All oxygen-breathing lifeforms take in Oxygen and exhale CO2. Plants take in the CO2 and use it in their photosynthesis process and in turn give off oxygen.

A:

The Carbon Dioxide-Oxygen Cycle is a continuously occurring process whereby animals inhale Oxygen and then exhale Carbon Dioxide, and plants use the CO2 and "exhale" O2.

A:

Plants and other producers use carbon dioxide in photosynthesis.
They produce oxygen as a waste product. Carbon dioxide moves
from the air into the leaves of plants. Oxygen moves from the
plant into the air through the leaves.

A:

Almost all living things, including plants, get energy from cellular
respiration. This process releases energy from the sugar molecules
in food. Oxygen is used in cellular respiration. Carbon dioxide is
produced as a waste product.

A:

The oxygen produced during photosynthesis is used in cellular
respiration. The carbon dioxide produced in cellular respiration is
used in photosynthesis. carbon dioxide and oxygen move through the ecosystem in this path called the CARBON DIOXIDE-OXYGEN CYCLE.

A:


During photosynthesis, algaet green plants take in CO2 from the air. They use CO2, along with H2O and the sun's energy, to make their own food (respiration). In this process, O2 is released as a waste product. Plants and animals need this oxygen to release energy from food.


A:

During photosynthesis green plants take in CO2 from the air. They use CO2 along with H2O and the sun's energy to make their own food (respiration). In this process O2 is released as a waste product. Plants and Animals need O2 to release energy from food. In the process O2 is taken in and CO2 is released. Carbon is also released as CO2 when organisms die and decay (work of decomposers).

A:

The carbon dioxide-oxygen cycle is the cycle in which living things (such as plants and animals) take in "oxygen" and let out "carbon dioxide."

A:

Humans & plants. Humans inhale oxygen, which is what plants excrete, and then the human excretes carbon dioxide, which the plants take in.

A.
In short plants release oxygen , that animals will take in and animals excrete carbon dioxide for the plants to produce their own food through photosynthesis .

Water Cycle

The Water Cycle (also known as the hydrologic cycle) is the journey water takes as it circulates from the land to the sky and back again.

The Sun's heat provides energy to evaporate water from the Earth's surface (oceans, lakes, etc.). Plants also lose water to the air (this is called transpiration). The water vapor eventually condenses, forming tiny droplets in clouds. When the clouds meet cool air over land, precipitation (rain, sleet, or snow) is triggered, and water returns to the land (or sea). Some of the precipitation soaks into the ground. Some of the underground water is trapped between rock or clay layers; this is called groundwater. But most of the water flows downhill as runoff (above ground or underground), eventually returning to the seas as slightly salty water.

WHY ARE THE OCEANS SALTY?


Oceans cover about 70% of the Earth's surface. The oceans contain roughly 97% of the Earth's water supply.
As water flows through rivers, it picks up small amounts of mineral salts from the rocks and soil of the river beds. This very-slightly salty water flows into the oceans and seas. The water in the oceans only leaves by evaporating (and the freezing of polar ice), but the salt remains dissolved in the ocean - it does not evaporate. So the remaining water gets saltier and saltier as time passes.

Energy Pyramid Part 1

An energy pyramid is a graphical model of energy flow in a community. The different levels represent different groups of organisms that might compose a food chain. From the bottom-up, they are as follows:
  • Producers — bring energy from nonliving sources into the community
  • Primary consumers — eat the producers, which makes them herbivores in most communities
  • Secondary consumers — eat the primary consumers, which makes them carnivores
  • Tertiary consumers — eat the secondary consumers
In some food chains, there is a fourth consumer level, and rarely, a fifth. Have you ever wondered why there are limits to the lengths of food chains?

Why are energy pyramids shaped the way they are?

An energy pyramid’s shape shows how the amount of useful energy that enters each level — chemical energy in the form of food — decreases as it is used by the organisms in that level. How does this happen?
Recall that cell respiration “burns” food to release its energy, and in doing so, produces ATP, which carries some of the energy as well as heat, which carries the rest. ATP is then used to fuel countless life processes. The consequence is that even though a lot of energy may be taken in at any level, the energy that ends up being stored there – which is the food available to the next level — is far less. Scientists have calculated that an average of 90% of the energy entering each step of the food chain is “lost” this way (although the total amount in the system remains unchanged).
The consumers at the top of a food pyramid, as a group, thus have much less energy available to support them than those closer to the bottom. That’s why their numbers are relatively few in most communities. Eventually, the amount of useful energy left can’t support another level. That’s why energy flow is depicted in the shape of a pyramid. The energy that enters a community is ultimately lost to the living world as heat.

Food Chain and Food Web Summary

What is the difference between food chain and a food web?

FOOD CHAINS FOLLOW A SINGLE PATH AS ANIMALS EAT EACH OTHER.
EXAMPLE:
  • THE SUN provides food for GRASS
  • The GRASS is eaten by a GRASSHOPPER
  • The GRASSHOPPER is eaten by a FROG
  • The FROG is eaten by a SNAKE
  • The SNAKE is eaten by a HAWK.

FOOD WEBS SHOW HOW PLANTS & ANIMALS ARE INTERCONNECTED BY DIFFERENT PATHS.

EXAMPLE:
  • TREES produce ACORNS which act as food for many MICE and INSECTS.
  • Because there are many MICE, WEASELS and SNAKES have food.
  • The insects and the acorns also attract BIRDS, SKUNKS, and OPOSSUMS.
  • With the SKUNKS, OPPOSUMS, WEASELS and MICE around, HAWKS, FOXES, and OWLS can find food.
  • They are all connected! Like a spiders web, if one part is removed, it can affect the whole web.
FOOD WEBS show how plants and animals are connected in many ways to help them all survive. FOOD CHAINS follow just one path of energy as animals find food.

Nalood na ako sa Energy Pyramid

An energy pyramid is the graphical representation of the trophic levels (nutritional) by which the incoming solar energy is transferred into an ecosystem. The source of energy for living beings on Earth is the Sun. The energy that the Sun emits at present is of 1366.75 W/m^2 (400 years ago, it was of 1363.48 W/m^2). When the studies of the capture of energy by the producer organisms (photosynthetic organisms) were made, the Solar Irradiance (SI) was of 1365.45 W/m^2. The energy usable by photosynthetic organisms is 697.04 W/m^2; nevertheless, the photosynthetic organisms take only 0.65 W/m^2 and the rest of the incident energy on the surface is transferred to the abiotic surroundings (oceans, soil, atmosphere, etc.) and from there, the energy is emitted to the outer space and to the Gravity field (Guth. 1999. Pp. 29-31). The atmosphere absorbs 191.345 W/m^2, maintaining the tropospheric temperature of Earth in the hospitable 35.40 °C (95.72 °F).

On the diagram, the ciphers expressed in the boxes at the left side of the pyramid represent the energy taken by each individual. For example, the amount of energy acquired by the herbivores is equivalent to the ingestion of one gram of organic material from photosynthetic organisms. Each subsequent amount of energy (green rectangle) in the pyramid (towards the peak) is the energy that would be obtained by each gram of organic material originated from the underlying level. Detritivores or detritivorous are organisms that fed on remnants of organic matter, like corpses, excrements, etc. Detritivores take advantage of ca. 57% from the energy stored by the producers.

Food Chain and Food Web

Do you like to play games? If you do, you will need energy. Every time you run or jump, you are using up energy in your body. How do you get the energy to play? You get energy from the food you eat. Similarly, all living things get energy from their food so that they can move and grow. As food passes through the body, some of it is digested. This process of digestion releases energy.

A food chain shows how each living thing gets its food. Some animals eat plants and some animals eat other animals. For example, a simple food chain links the trees & shrubs, the giraffes (that eat trees & shrubs), and the lions (that eat the giraffes). Each link in this chain is food for the next link. A food chain always starts with plant life and ends with an animal.


  1. Plants are called producers because they are able to use light energy from the Sun to produce food (sugar) from carbon dioxide and water.
  2. Animals cannot make their own food so they must eat plants and/or other animals. They are called consumers. There are three groups of consumers.

    1. Animals that eat ONLY PLANTS are called herbivores (or primary consumers).
    2. Animals that eat OTHER ANIMALS are called carnivores.

      • carnivores that eat herbivores are called secondary consumers
      • carnivores that eat other carnivores are called tertiary consumers
        e.g., killer whales in an ocean food web ... phytoplankton → small fishes → seals → killer whales

  3. Animals and people who eat BOTH animals and plants are called omnivores.
  4. Then there are decomposers (bacteria and fungi) which feed on decaying matter.

    These decomposers speed up the decaying process that releases mineral salts back into the food chain for absorption by plants as nutrients.

    Image Map of the Nitrogen Cycle - What happens in the soil?
Do you know why there are more herbivores than carnivores?

In a food chain, energy is passed from one link to another. When a herbivore eats, only a fraction of the energy (that it gets from the plant food) becomes new body mass; the rest of the energy is lost as waste or used up by the herbivore to carry out its life processes (e.g., movement, digestion, reproduction). Therefore, when the herbivore is eaten by a carnivore, it passes only a small amount of total energy (that it has received) to the carnivore. Of the energy transferred from the herbivore to the carnivore, some energy will be "wasted" or "used up" by the carnivore. The carnivore then has to eat many herbivores to get enough energy to grow.

Because of the large amount of energy that is lost at each link, the amount of energy that is transferred gets lesser and lesser ...


  1. The further along the food chain you go, the less food (and hence energy) remains available.
  2. The above energy pyramid shows many trees & shrubs providing food and energy to giraffes. Note that as we go up, there are fewer giraffes than trees & shrubs and even fewer lions than giraffes ... as we go further along a food chain, there are fewer and fewer consumers. In other words, a large mass of living things at the base is required to support a few at the top ... many herbivores are needed to support a few carnivores
  3. Most food chains have no more than four or five links.

    There cannot be too many links in a single food chain because the animals at the end of the chain would not get enough food (and hence energy) to stay alive.

    Most animals are part of more than one food chain and eat more than one kind of food in order to meet their food and energy requirements. These interconnected food chains form a food web
  4. A change in the size of one population in a food chain will affect other populations.

    This interdependence of the populations within a food chain helps to maintain the balance of plant and animal populations within a community. For example, when there are too many giraffes; there will be insufficient trees and shrubs for all of them to eat. Many giraffes will starve and die. Fewer giraffes means more time for the trees and shrubs to grow to maturity and multiply. Fewer giraffes also means less food is available for the lions to eat and some lions will starve to death. When there are fewer lions, the giraffe population will increase.

Interaction Among Organisms(Symbiotic Relationship)

There are 6 different kinds of symbiotic relationships:
  1. Mutualism, where both species benefit
  2. Commensalism, where one species benefits, the other is unaffected
  3. Parasitism, where one species benefits, the other is harmed
  4. Competition, where neither species benefits
  5. Neutralism, where both species are unaffected
  6. Predation, one of the animal is the predator and the other one is the prey.
Examples:
Mutualism- honeybee and flower
Commensalism- arctic fox and caribou
Parasitism- puppy and roundworm

Basics of Ecology

Ecology (from Greek: οἶκος, "house"; -λογία, "study of") is the scientific study of the relations that living organisms have with respect to each other and their natural environment. Variables of interest to ecologists include the composition, distribution, amount (biomass), number, and changing states of organisms within and among ecosystems. Ecosystems are hierarchical systems that are organized into a graded series of regularly interacting and semi-independent parts (e.g., species) that aggregate into higher orders of complex integrated wholes (e.g., communities). Ecosystems are sustained by the biodiversity within them. Biodiversity is the full-scale of life and its processes, including genes, species and ecosystems forming lineages that integrate into a complex and regenerative spatial arrangement of types, forms, and interactions. Ecosystems create biophysical feedback mechanisms between living (biotic) and nonliving (abiotic) components of the planet. These feedback loops regulate and sustain local communities, continental climate systems, and global biogeochemical cycles.

Ecological Organization Pyramid:

The study of ecology has many layers, ranging from the individual organism, to the population, to the ecosystem, to the planet. It is important for students to know the levels within this hierarchy and to recognize which level they are focusing on at any one time. For the purposes of this activity, students will learn about the different levels (organism, population, community, ecosystem, biome, and biosphere) by choosing an organism and the illustrating a pyramid about that organism. The result is a colorful display of organizational pyramids.
Objectives
