Storyboard Text

  • Hello, my name is Bob. I have nitrogen cells in me. Today i'm going to talk about nitrogen cycle. My nitrogen cells get distributed through my waste. It then goes through ammonification. 
  • The process of ammonification converts organic nitrogen, which is the way nitrogen is contained in compounds in living organisms, into inorganic ammonia (NH3) or ammonium ions (NH4+). 
  • Once the cell is inorganic ammonia, it then must go through nitrification or assimilation. Nitrification is The process by which bacteria in soil and water oxidize ammonia and ammonium ions and form nitrites and nitrates. Nitrification is very important because it can be absorbed by very important organisms
  • Assimilation is when plants and animals incorporate the ammonia formed through nitrification. Plants take up these forms of nitrogen through their roots, and incorporate them into plant proteins and nucleic acids. Once we have done assimilation we move on to denifitrication
  • Denitrification is exactly what it sounds like. It is opposite process of nitrification. During this, nitrates are reduced to nitrites and then to nitrogen gas and ammonia. Next we must go to Nitrogen fixation. 
  • Nitrogen fixation is a process by which nitrogen in the air is converted into ammonia (NH3) or related nitrogenous compounds. I also breathe in this nitrogen and again, it goes through my waist
