The Nitrogen Cycle is a key geochemical process that allows an ecosystem to function. Nitrogen is used by biological organisms to build amino acids, nucleic acids and proteins. As a pure element, nitrogen is inert, and must be fixed into organic molecules, such as ammonia and nitrates. This is accomplished by bacteria and fungi. Nitrogen is then passed through the food chain and back into the soil by the decomposition of organic matter. The nitrogen cycle is a crucial component in the functioning of ecosystems because it is intrinsic to the functioning of a food pyramid. Rain Forest Rain forests have a large variety of primary producers (as vegetation) and consumers occupying the various levels of it
