Assimilation
Nitrification
Nitrosomonas converts to Nitrite (NO2-)
(Begin) Nitrification is when:
(Begin) Denitrification happens when:
Nitrogen Fixing Bacteria can be free-living (Azobacter) or Mutualistic (Rhizobium)
Nitrogen Fixation
Ammonification
into the soil by breaking the bonds of molecular nitrogen.
The breakdown of organic nitrogen into ammonia and its release as waste to reenter the cycle.
(Begin) The nitrogen cycle occurs in general phases:
that convert Nitrogen Gas (N2) in the atmosphere into Ammonia (NH3)
(Begin) Ammonification is:
the denitriying bacteria such as Pseudomonas denitrificans
Abiotic Fixation (Lightning) and Biotic Fixation (Nitrogen-Fixing Bacteria)
(Begin) Nitrogen fixation involves:
and after being exposed to water: Ammonium (NH4+)
(Begin) Assimilation occurs when:
Ammonia or Ammonium is converted by nitrifying bacteria.
Animals consume the tissues and absorb the nitrates.
Plants take in nitrate through their roots and incorporate them into tissues.
Nitrobacter oxidizes to Nitrate (NO3-)
breaks down Nitrate into Nitrogen Gas
Denitrification
