What does nitrogen Fixation mean?
the first step in the process of making nitrogen usable by plants.
the process by which ammonia is converted to nitrites (NO2-) and then nitrates (NO3-).
(some free-living bacteria and fungi ) break down animal and plant proteins (from dead organisms) and nitrogenous waste products to release energy
the process that converts nitrate to nitrogen gas, thus removing bioavailable nitrogen and returning it to the atmosphere
