What is the role of a leech-looking worm in its ecosystem and how does it contribute to the environment?

Leech-looking worms, also known as oligochaetes, play a crucial role in their ecosystem by breaking down organic matter and recycling nutrients. They help to decompose dead plant material and animal remains, releasing nutrients back into the soil. This process enriches the soil and promotes plant growth, ultimately contributing to the overall health and balance of the environment.
