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
