Decomposers are organisms that break down dead plants and animals, returning essential nutrients to the soil. They play a crucial role in the ecosystem by recycling matter, which helps maintain a healthy environment. Common decomposers include fungi, bacteria, and some insects like earthworms. Without these organisms, waste would accumulate, and nutrients would be locked away, making it difficult for new life to thrive. These tiny workers are often overlooked, but they are vital for the growth of new plants. When decomposers break down organic material, they release nutrients like nitrogen and phosphorus back into the soil, which are essential for the health of living organisms.
