The nitrogen cycle is the series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.

Step 1 - Nitrogen Fixation - Nitrogen is absorbed into organic compounds

Step 2 - Nitrification - oxidation of ammonia or ammonium to nitrite

Step 3 - Ammonification - Bacteria or fungi convert the organic nitrogen within the remains back into ammonium

Step 4 - Denitrification -  the loss or removal of nitrogen or nitrogen compounds
