How Does the Nitrogen Cycle Work?


The nitrogen cycle works this way: Plant and animal wastes decompose and add nitrogen to the soil. Bacteria in the soil convert these forms of nitrogen into forms plants use. Plants use the nitrogen in the soil to grow. People and animals eat the plants, then animal and plant residues return nitrogen to the soil again, completing the cycle.
