Storyboard Text

  • The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into various chemical forms as it passes through the atmosphere, terrestrial, and marine ecosystems
  • HI my name is billy and me and my friends are going to tell you about the nitrogen Cycle
  • Process 1# Nitrogen Fixation
  • Nitrogen fixation is a process in which nitrogen (N2) in the Earth's atmosphere is converted into ammonia (NH3) witch plants use to make protien
  • Process 2# Nitrification
  • Nitrification is the biological oxidation of ammonia or ammonium to nitrite followed by the oxidation of the nitrite to nitrate
  • Process 3# Ammonification
  • Ammonification is the process by which the organically bound nitrogen of microbial, plant, and animal biomass is recycled after their death
  • Process 4# Denitrification
  • Denitrification is a microbially facilitated process of nitrate reduction (performed by a large group of heterotrophic facultative anaerobic bacteria) that may ultimately produce molecular nitrogen (N2) through a series of intermediate gaseous nitrogen oxide products
  • I hope my friends helped you understand the nitrogen cycle. Sometimes it can be hard to understand but with a good explanation it is pretty easy
