What is the role of decomposers in an ecosystem?

Decomposers play a critical role in ecosystems by breaking down organic material, such as dead plants and animals, and recycling nutrients back into the soil. This process is essential for maintaining soil health and fertility, allowing plants to absorb these nutrients and continue growth. Decomposers, including fungi, bacteria, and some insects, convert complex organic substances into simpler compounds. This not only helps in nutrient cycling but also keeps the environment clean by decomposing waste materials. Essentially, they form a crucial link in the food web, helping to sustain the ecosystem by ensuring that nutrients are reused, fostering a balance that supports various life forms.
