How humans affect the nitrogen cycle
Web28 mei 2012 · The nitrogen cycle is a crucial biogeochemical cycle that recycles the element nitrogen (N 2) into its various usable forms. It is very similar to other cycles, such as the water and oxygen cycles. As such, the nitrogen cycle is extremely important in sustaining Earth's plentiful ecosystems. Nitrogen by itself is actually quite inert (does not ... WebTypes of Biogeochemical Cycles. There are two main types of biogeochemical cycles, namely gaseous cycles and sedimentary cycles: Gaseous cycles - examples are the carbon, nitrogen, oxygen and water cycles. The reservoirs of these cycles are the atmosphere or hydrosphere. Sedimentary cycles - examples are the phosphorus and …
