WebBacteria play a key role in the nitrogen cycle. Nitrogen enters the living world by way of bacteria and other single-celled prokaryotes, which convert atmospheric nitrogen— \text N_2 N2 —into biologically usable forms in a … WebWhat is a Biogeochemical Cycle? A biogeochemical cycle or an inorganic-organic cycle is a circulating or repeatable pathway by which either a chemical element or a molecule moves through both biotic (biosphere) and abiotic (lithosphere, atmosphere and hydrosphere) components of an ecosystem. Let us try to understand this definition. WebMay 7, 2024 · A component of a biogeochemical cycle that holds an element or water for a long period of time is called a reservoir. For example, the deep ocean is a reservoir for water. It may hold water for thousands of years. The rest of this concept takes a closer look at four particular biogeochemical cycles: the water, carbon, and nitrogen cycles software of excellence dental referrals
