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