The nitrogen cycle is one of the most important biogeochemical cycles. However, molecular nitrogen (N2) in the atmosphere is not a significant element for life because

• almost all nitrogen is in the atmosphere and therefore unavailable for life

• organisms use either CO2 or O2 but not nitrogen

• N2 is relatively inert and must be transformed in order to be useful

• where nitogen is insufficient, organisms can use other, more plentiful nutrients
