These … WebThe nitrogen cycle can be divided into several stages: Nitrogen fixation: This is the process by which atmospheric nitrogen (N2) is converted into ammonia (NH3) or nitrate (NO3-) ions. Nitrogen fixation is carried out by nitrogen-fixing bacteria found in the soil, as well as some cyanobacteria and algae.
