WebApr 13, 2024 · Like the spinning gears of a clock, the various biogeochemical cycles on Earth occur in tandem with one another. As a result, the continuation of one biogeochemical process can be impacted by the progression of a separate yet connected cycle. Such feedback can be observed in the nitrogen cycle. Nitrogen is essential for life … WebA similar process occurs in the marine nitrogen cycle, where these three processes are performed by marine bacteria and archaea. Human activity releases nitrogen into the environment by the use of artificial fertilizers that contain nitrogen and phosphorus compounds, which are then washed into lakes, rivers, and streams by surface runoff.
