Nitrogen Cycle!

reviews multiple steps of the nitrogen cycle and different forms of nitrogen created, used for APES
STUDY
PLAY
Nitrogen Fixation
conversion of N2 gas into usable NH4 (clouds->ground)
Nitrification
conversion of NH4 to NO3, first going through NO2 (all in ground)
Assimilation
uptake of usable nitrogen (NH4) by plants (ground->trees/plants)
Ammonification
organic nitrogen wastes convert/break down back to usable nitrogen forms (ground)
Denitrification
converting usable NH4 or NO3 into gas forms, N2 or N2O (ground -> air)
Nitrogen gas
N2, non usable
Nitrite
NO2 -, non usable
Ammonium
NH4, usable
Nitrate
NO3-, usable
Haber Process
Artificial process that take N2 and converts into chemical synthetic fertilizer, requires energy from fossil fuels
