    Nitrogen cycle is all about the movement of nitrogen between various elements on Earth (like air, soil, living organisms etc.) The amount of nitrogen in the atmosphere remains constant.

    • Atmosphere has approx. 78% nitrogen.
    • Atmospheric Nitrogen is fixed into the soil
      • N2 fixing microbes convert atm. N2 into nitrogen compounds like NH3
    • Plants utilize nitrogen from soil through their roots
    • Animals utilize nitrogen, feeding on plants
    • When Plants & animals die, Nitrogenous wastes are returned to soil
      • Decomposers convert some part to nitrogen compounds to be used by plants
      • Denitrifying bacteria convert into atm. N2
