A musical Lecture by Glenn Wolkenfeid
Oh a huclear happens deep inside the sun,
Where hydrogen atoms are fused into helium.
Then the heat and light is radiated into space.
In 90 milion miles it shines upon the Earth”s face.
For every hundred calories that shine out from the sun.
The calories that green plants trap will number only one.
But evry single calorie in ocean, hills, and plains,
Will serve as a foundation for a living food chain.
At the bottom of a food chain are producers like green plants.
Whose cells make food from sunlight making use of chloroplasts.
It happens in the pines and flowers on your windowsill.
Cause every single green plant”s got a little chlorophyll.
Well the next step in a food chain is a primary consumer,
An herbivoric cow or vegetarian baby boomer.
A primary consumer spends it”s mealtimes eating plant.
It might be buffalo or might be an ant.
Each level in a food chain yields only ten percent,
Of the former level’s energy you might ask where it went.
There are bones and leaves you can’t digest that really make a dent.
And don’t ignore the weighty cost of metabolic rent.
So if your plant are yieding bout a hundred calories.
Your yield will only be ten in the birdies and the bees.
And seven hundred calories in algae in the sea,
In primary consumers it will yield you seventy.
Some other ways of getting food are really out of sight.
You could be a predator or be a parasite.
A predator eats meat, a parasite eats your insites,
And if you’re a decompoer you will eat me when I die!
And if you know this ‘bout food chains you can really take the cake.
When energy gose through it dosen’t last, it dissipates.
But hutrients infood chains meet a very different fate,
They recycle and they circulate forever, ain’t that great!
Just remember ther’s no beings in this world that live alone.
Populations form communities, where all do make their homes.
Though your niche may be determining the role that you are playing,
Every creature live or dead is in s food chain!
