What are decomposers?

Decomposers are organisms that break down dead plants, animals, and organic waste into simpler substances, allowing nutrients to return to the environment.

They play a crucial role in ecosystems by ensuring that organic matter does not accumulate and that essential elements are recycled back into the soil.

The main types of decomposers include:

• Bacteria - break down organic matter at a microscopic level
• Fungi - such as mushrooms and molds, which decompose tough materials like wood

These organisms release enzymes that chemically break complex substances into simpler compounds that plants can reuse.

Functional role:
Without decomposers, nutrients would remain locked in dead matter, and ecosystems would eventually collapse due to lack of nutrient recycling.
