Cells that take nitrogen in the air and make to a form that plants can take in from the soil.
heterocysts
nitrogen fixing is a process in which atmosphere nitrogen converted into ammonia.
nitrogen fixing is a process in which atmosphere nitrogen converted into ammonia.
Nitrogen-fixing bacteria
Nitrogen fixation is a uniquely prokaryotic. This a one celled organism.
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.
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.
Chemoautotrophs like Nitrogen fixing bacteria
They differentiate a select few cells into specialized semi-anaerobic nitrogen fixing cells called heterocysts.
