Answer:
nitrogen cycle
Explanation:
Decomposers are saprophytic organisms which include bacteria and fungi. The decomposers act on the dead organic matter to release inorganic materials. Green plants absorb these nutrients and through photosynthesis, the nutrients are used in the synthesis of organic compounds.
Animals feed on plants and assimilate the plant proteins into animal proteins. When plants and animals die, they are acted upon by saprophytic bacteria and fungi forming ammonium compounds which can be absorbed by plants.
