Storyboard Text

  • Hi there! I'm Dan!
  • And i'm kelly!
  • we're going to teach you about the nitrogen cycle!
  • It  all starts in the soil, when bacteria absorb the atmospheric nitrogen(NH2), and turn it into ammonia. This process is called nitrogen fixation.
  • Decaying Plant and animal remains can also create ammonia.
  • After this the legumes in the plants roots turn the ammonia into nitrates.
  • atmospheric and industrial fixation creates nitrates directly into the soil.
  • The plant absorbs most of the nitrates, but some get denitrified by bacteria and gets put back into the atmosphere.
  • Thanks for listening!
