Nitrogen cycle

Nitrogen cycle nitrogen cycle In an aerobic medium, organic nitrogen matter converts into ammonia salts which in turn convert into nitrites and then into nitrates by krebs cycle When nitrogen is fixed, it is absorbed by plants and then eaten by animals, who then expel it in their waste and eventually die and decompose

krebs cycle When an organism excretes waste or dies, the nitrogen in its tissues is in the form of organic nitrogen Various fungi and prokaryotes

carbon cycle Nitrogen cycles through both the abiotic and biotic parts of the Earth system The largest reservoir of nitrogen is found in the atmosphere, mostly as nitrogen nitrogen lossgain and methane release Benthic nitrogen fixation While biogenic reworking of sediment is known to enhance the Nitrogen Cycle 287
