Question

What is nitrogen fixation​

Answer 1

Answer: Nitrogen fixation is a process by which molecular nitrogen in the air is converted into ammonia (NH₃) or related nitrogenous compounds in soil. Atmospheric nitrogen is molecular dinitrogen, a relatively unreactive molecule that is metabolically useless to all but a few microorganisms. Biological nitrogen fixation converts N₂ into ammonia, which is metabolized by most organisms.
