Nitrogen is essential to all living organisms — it is a core component of proteins, nucleic acids, and chlorophyll — yet most of Earth&rsquo;s nitrogen (78% of the atmosphere) is locked in inert molecular form (N₂) that most organisms cannot use. The nitrogen cycle describes how this unavailable nitrogen becomes biologically available and how it cycles through life and back to the atmosphere.</p>
