The Nitrogen Cycle

The Nitrogen Cycle

The nitrogen cycle is a crucial biogeochemical process that transforms nitrogen through its various chemical forms within the environment. Nitrogen is an essential element for all life, playing a fundamental role in the structure of proteins, nucleic acids, and other vital organic molecules. Although abundant in the atmosphere as diatomic nitrogen gas (N₂), this form is largely unusable by most organisms, necessitating its conversion into more reactive compounds.
