The nitrate cycle
WebThe nitrogen cycle is a model that explains how nitrogen is recycled. There's lot of nitrogen in the air - about 78 per cent of the air is nitrogen. Because nitrogen is so unreactive, it... WebThe nitrogen cycle is the biogeochemical cycle that describes the movement and transformation of nitrogen in various forms through the biosphere. Nitrogen is an essential element for living organisms, and it is necessary for the formation of DNA, RNA, and proteins. However, most organisms cannot use nitrogen in its atmospheric form (N2), …

WebThis type of cycle of atoms between living and non-living things is known as a biogeochemical cycle. All of the atoms that are building blocks of living things are a part of biogeochemical cycles. The most common of these are the carbon and nitrogen cycles. Tiny atoms of carbon and nitrogen are able to move around the planet through these cycles.
