Nitrogen Cycle
  1. Nitrogen Fixation
    1. Ammonia (NH3)
      1. Ammonium (NH4+)
        1. Plants
          1. Animals
            1. Plants > Animals via Ingestion
                1. Animal > NH4+ by putrification
              1. NH3 > Plants via absorption from roots
                  1. Plants > NH4+ by De-amnifiaction
                  2. NO3- > Plants via absorption from root
                  3. NH3 > NH4+ By dissolving
                    1. Nitrites (NO2-)
                      1. Nitrates (NO3-)
                        1. NO2- > NO3- by Nitrification using Nitrosomonas
                              1. NO3- > N2 via de-nitrification
                              2. NH3 > NO2- by Nitrification using Nitrosomes
