WebJun 7, 2011 · Nitrogen fixation is an essential process that biologically transforms atmospheric dinitrogen gas to ammonia, therefore compensating for nitrogen losses occurring via denitrification and anammox. Currently, inputs and losses of nitrogen to the ocean resulting from these processes are thought to be spatially separated: nitrogen … WebBacteria play a key role in the nitrogen cycle. Nitrogen enters the living world by way of bacteria and other single-celled prokaryotes, which convert atmospheric nitrogen— \text N_2 N2 —into biologically usable forms in a …
WebDenitrification is a biological process of reduction in which the nitrogen compounds are released back into the atmosphere in their gaseous form – nitrogen gas (N) by the conversion of nitrate (NO 3– ). Therefore, this is the final stage of the nitrogen cycle, carried on without oxygen. The entire process of denitrification is carried out ...
