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