Nitrogen (N2) is converted through chemical processes such as combustion, volcanic action, lightning discharges, industrial means, and bacteria to ammonia (NH3)
Reduced forms of inorganic and organic nitrogen, particularly ammonium (NH4), are converted to nitrite then oxidized to nitrate (NO3)
Plants absorb nitrate and ammonia through their roots and use them for plant proteins and nucleic acids. Animals utilize nitrogen from plant tissues.
Bacteria reduces nitrate (NO3) into nitrogen (N2), which escapes into the air.
Nitrate from the soil can leave the soil in drainage water and pollute fresh water bodies.
Runoff into ocean
Fertilizer from factories and farms are dumped into rivers and eventually flow into the sea.
Bacteria's job (denitrifying and nitrifying)
they take in one form of nitrogen use it and release a different form of nitrogen as waste
releases ammonium back into soil
Plants and algae job's
Take in ammonium in small amounts and nitrate in large amounts
