13 11/23/2018 Nitrogen Cycle Atmospheric nitrogen (N2) cannot be used by most organisms Ammonification passing ammonia from animals through decay or urine Nitrogen fixation lightning, biological, industrial Only bacteria found in soil and nodules of plants can change to usable form by ‘fixation’ Change to NH3 Assimilation use of ammonia and nitrates by plants and then to animals Nitrification used by plants changing nitrogen into nitrates or nitrites Denitrification bacteria (anaerobic) that use nitrogen as final electron acceptor of respiration and pass N2 back into the atmosphere

Cycles Matter can cycle through the biosphere because biological systems do not use up matter, they transform it. Matter is Recycled within and between.
