Nitrogen Cycle

The nitrogen cycle is a biogeochemical cycle that converts nitrogen into various forms throughout the ecosystem. Nitrogen is an essential element for life that organisms use in the synthesis of amino acids, proteins, and nucleic acids. Yet, while the atmosphere is rich in nitrogen (about 78%), this nitrogen (N 2) is largely inaccessible to ...
