Final answer:
Decomposers break down dead organic matter, recycle nutrients, and help keep the ecosystem clean and healthy.
Step-by-step explanation:
Decomposers play a vital role in an ecosystem by breaking down dead organic matter, such as leaves, dead animals, and waste products, into simpler compounds. They are primarily responsible for the recycling of nutrients back into the ecosystem. Decomposers, such as bacteria and fungi, release enzymes that break down complex molecules, allowing them to be absorbed by plants and reused.
For example, in a forest ecosystem, decomposers like earthworms, fungi, and bacteria break down fallen leaves, dead animals, and other organic matter. Through the process of decomposition, these organisms convert the complex organic compounds into simpler forms, releasing nutrients like nitrogen and phosphorus that can be taken up by plants and used for growth.
In addition to nutrient recycling, decomposers also help in the decomposition of waste materials and the removal of dead organisms, preventing the accumulation of dead matter. This process helps keep the ecosystem clean and healthy.
