The nitrogen cycle is complex then in part because of the many chemical forms of N such as: Organic-N; NO3; NH4; and the gases N2, N2O, NO + NO2 (=NOx). Figure 10 below gives an overview of the global nitrogen cycle. Figure 10. The Global Nitrogen Cycle. Accounting . Just as we did for the water cycle, or first step in understanding the nitrogen cycle is to examine the distribution of N on ...

NITROGEN CYCLE • Is an atmospheric cycle. • Plants and animals cannot use free nitrogen gas in the atmosphere. They must have nitrogen in "fixed" form. Nitrogen is required for proteins, nucleic acids in living things. • Free N2 in atmosphere is "fixed" by nitrogen-fixing bacteria and/or lightning (nitrogen-fixation) to NH3 (ammonia):
