The nitrogen which plants and animals use is produced by bacteria. Bacteria in the soil changes nitrogen in the atmosphere (N2) into ammonia (NH3), a form that plants can use.

Name the nitrogen fixing bacteria?

The Rhizobium or Bradyrhizobium bacteria colonize the host plant's root system and cause the roots to form nodules to house the bacteria and fix the nitrogen.

When plants, animals, and other organisms die, decomposers return nitrogen to the soil.
