chemical form usable to living organisms, the path it travels through
biological processes, and how it is eventually returned to dinitrogen
is the nitrogen cycle.
Nitrogen begins its journey into the
realm of living organisms via a process known as nitrogen fixation.
Fixation occurs mainly when microorganisms having the nitrogenase
enzyme extract dinitrogen from the air and convert it to ammonia. These
microorganisms may be free-living or may be symbiotic with plants.
