🎵 Luyện Nghe Bài Hát: Food Chains - Glenn Wolkenfeld

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