107. Four processes participate in the cycling of nitrogen through the biosphere:
Nitrogen fixation: Break apart N2 so it can join to other atoms and be used.
Nitrification: Plants with bacteria take up nitrogen.
Decay: Passes on through eating / waste.
Denitrification: Nitrogen returned to the air by bacteria.
Happens with poor soil management.
