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.
