🎵 Luyện Nghe Bài Hát: Food Chains - Glenn Wolkenfeld

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