🎵 Luyện Nghe Bài Hát: Food Chains - Glenn Wolkenfeld

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