Nitrogen-fixing bacteria
Nitrogen fixation is a uniquely prokaryotic. This a one celled organism.
Nitrogen-fixing bacteria
Reactions for the formation of oxides of nitrogen and nitrates as nitrogen fixing
Nitrogen-fixing bacteria help cycle nitrogen through the ecosystems in a variety of ways. With plants, the nitrogen-fixing bacteria help ensure that nitrogen is cycled back into the soil.
The air.
carnivores -> herbivores -> plants -> nitrogen fixing bacteria
Nitrogen-fixing bacteria do reduce the amount of nitrogen in the atmosphere by converting N2 into ammonia.
The Encyclopedia Britannica has a lot of great information on nitrogen fixing bacteria. According to the Encyclopedia Britannica nitrogen fixing bacteria are microorganisms capable of transforming atmospheric nitrogen into fixed nitrogen.
