- Nitrates in the sil are absorbed by the plants and are also put back into the atmosphere by denitrifying bacteria.
- The plants decompose into ammonium compunds, and animals eat the plants and either poo or decompose into ammonium compounds. Nitrifying bacteria turns ammonium compounds back into nitrates in the soil.
- Nitrogen fixing bacteria are found in the soil and the roots of the plants.
- Lightning can also put nitrogen in the soil.
- Taking plants out of the ground removes that nitrogen from the cycle.
