• Nitrogen cycle in aquatic ecosystem - SlideShare

  The circuit established between nitrogen fixation, nitrification, and denitrification/annamox reactions form the main nitrogen cycle in aquatic environments. The complete cycle involves a set of three coupled reduction/oxidation/reduction reactions, which are either alternatively sensitive to, or dependent upon oxygen.

  Then the nitrogen gets used in amino acids, nucleic acids, and chlorophyll. Ammonification - This is part of the decaying process. When a plant or animal dies, decomposers like fungi and bacteria turn the nitrogen back in ammonium so it can reenter the nitrogen cycle. Denitrification - Extra nitrogen in the soil gets put back out into the air.
