1 Decomposers and scavengers break down dead plants and animals. They also break down the waste (poop) of other organisms. Decomposers are very important for any ecosystem. If they weren't in the ecosystem, the plants would not get essential nutrients, and dead matter and waste would pile up.

2 the Chemical elements essential for life in living organisma are called Biogenic elements or Nutrient elements . these nutrients move from living to non.living to living portions of ecosystem in a cyclic manner Called \(\Large {Biogeochemical}{Cycles}\) or Nutrients cycles . e.g The Nitrogen Cycle
