In three to five sentences, describe what would happen to ecosystems if decomposers did not exist on Earth. Make sure your explanation includes a definition of decomposers.(4 points)

Answer 1

Decomposers are organisms, such as bacteria and fungi, that break down dead organic matter and recycle nutrients back into the ecosystem. If decomposers did not exist, dead plants and animals would accumulate, leading to a buildup of waste and a depletion of essential nutrients in the soil. This would cause disruptions in nutrient cycles, negatively impacting plant growth and the overall health of ecosystems. Over time, the absence of decomposers would result in a decline in biodiversity and the collapse of food webs, ultimately jeopardizing the survival of various species.
