A CONTINUAL PROCESS · Biological nitrogen fixation is the first step in the nitrogen cycle, occurring when atmospheric nitrogen is 'fixed' or converted into

Role of Organisms in Nitrogen Cycle · Nitrogen-fixing bacteria, which convert atmospheric nitrogen to nitrates · Bacteria of decay, which convert decaying

product life cycle Nitrogen transforms into several different forms in the 4 steps of the nitrogen cycle

calvin cycle Nitrogen Sinks The primary reservoir for long-term storage of nitrogen is nitrogen gas in the atmosphere However, there are other, smaller nitrogen sinks in
