Answer:
Hope ur referring to the nitrogen cycle, but here goes: basically, u can start anywhere in the nitrogen cycle to describe what happens to that nitrogen. For instance, you can start in the atmosphere. Nitrogen makes up a considerable amount of the Earth's atmosphere. This nitrogen is fixated by nitrogen-fixating bacteria and is converted into ammonia, a form that can be absorbed by organisms. This enters into the ecosystem. When plants/animals that have nitrogen in their systems die, the nitrogen is returned into the soil. Some plants cannot absorb ammonia however. So, a process known as nitrification also takes place. This is when ammonia is then converted into substances known as nitrites and nitrates, which are then absorbed. Lastly, denitrifying prokaryotes convert nitrates back into atmospheric nitrogen. Thus is the cycle.
