Answer:

Nitrogen fixation is the process by which the free nitrogen from the atmosphere is converted into the form of nitrates and nitrites which are then uptaken by the organisms

Explanation: It's the conversion of atmospheric nitrogen(N₂) to other nitrogen compounds like ammonia, nitrates, and nitrites.
