Nitrogen CycleThe atmosphere is 78% nitrogen gas
-this is NOT usable by living things. It must be converted using Nitrogen Fixation
Nitrogen cycle is a fast process. Most of the reservoirs hold nitrogen compounds
for relatively short periods of time
Nitrogen is a limiting nutrient in most ecosystems
Key Processes
Nitrogen Fixation
Coverts atmospheric nitrogen into a form that is readily usable by producers
(plants)
Biotic Fixation
● carried out by bacteria
● creates ammonia (NH2)
Abiotic Fixation
● carried out by lightning & artificial fertilizer production
● creates ammonium (NH4+)
Other Processes
Nitrification
● nitrifying bacteria convert ammonium (from abiotic fixation) into nitrite and
then into nitrate
