Storyboard Text

  • Welcome, today we will be talking about the Nitrogen Cycle.
  • Fine, the Nitrogen cycle starts with Nitrogen Fixation.
  • Yes, that's right. Nitrogen Fixation is the process in which Special bacteria convert the nitrogen gasses from the atmosphere into ammonia which plants can use.
  • Step two is Nitrification.
  • That's right Ginger Santa
  • Nitrification is the process which converts ammonia into nitrite ions which the plants can use to make proteins.
  • Bye
  • Bye Ginger Santa. The proteins then go through the food chain.
  • After all the living organisms use the nitrogen in the proteins, decomposer bacteria convert the nitrogen-rich waste compounds into simpiler ones in the process of Ammonification
  • Denitrification is the final step in which other bacteria convert the simple nitrogen compounds back into nitrogen gas.
  • That nitrogen gas is then released back into the atmosphere to begin the cycle again.
