It cannot be used by organisms until it is combined with another element. Nitrogen fixation is the process by which nitrogen gas in the atmosphere is converted into compounds like ammonia that can be used by living organisms for various biological processes. Nitrogen in its atmospheric form (N2) is inert and cannot be directly utilized by most organisms.
