  • Bacteria and fungi in the soil brake down (decompose) the dead plants and animals
    • The nitrogen in the dead plants and animals, urea and egested materials is broken down and returned to the soil as Ammonia
      • The nitrogen is converted into nitrates which are taken up by the roots of plants
        • Nitrogen in the proteins making up the bodies of plants
          • The nitrates are transferred to animals by feeding
            • Nitrogen in the proteins making up the bodies of animals
              • Excretion of urea
