WebJan 25, 2024 · The nitrogen cycle is a biogeochemical process through which Nitrogen passes and gets converted to a variety of forms, Nitrogen moves from soil to plant to animal and then back to soil and atmosphere in different consecutive processes. The different consecutive processes running simultaneously are: Nitrogen fixation. WebFixation. Nitrogen in its gaseous form (N 2) can’t be used by most living things. (Plants for example, do not have the required enzymes to make use of atmospheric nitrogen.) It has to be converted or ‘fixed’ to a more usable form through a process called fixation. There are three ways nitrogen can be fixed to be useful for living things: WebThe bacteria take gaseous nitrogen from the air in the soil and feed this nitrogen to the legumes; in exchange the plant provides carbohydrates to the bacteria. ...
