The biochemical cycle that involves the use of nitrogen by bacteria to later be used by plants is the nitrogen cycle.
Each of the biological processes (of plants, animals and microorganisms) and abiotic processes that allow the supply and transit of nitrogen is called the nitrogen cycle.
Nitrogen is fixed by bacteria and other prokaryotes through various metabolic processes, which convert it into different usable compounds, such as ammonia (NH3) and ammonium ion (NH4+).
Therefore, we can conclude that nitrogen through the cycle processes is converted into a usable form by plants.
