In an ecosystem, what role do decomposers, such as many fungi and bacteria, play?

Explanation

Decomposers, including many species of fungi and bacteria, play a critical ecological role by breaking down dead plants, animals, and other organic waste material into simpler substances, releasing valuable nutrients back into the soil where they can be reused by producers like plants. Without decomposers, dead organic matter would accumulate indefinitely, and essential nutrients would remain locked away rather than cycling back through the ecosystem. This recycling process makes decomposers an essential, though often overlooked, component of virtually every ecosystem on Earth. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
