WebThe nitrogen cycle consists of fluxes (Table 4.2) between the reservoirs (Table 4.1). Because most organisms are not capable of capturing N 2 and “fixing” it into reduced nitrogen for biological processes, the distinction between N 2 (and N 2 O) and all other forms of nitrogen is a mean-ingful one.
