👉 The term "earthworm" is a general name for various types of worms, including the ones commonly found on land and in water bodies. These worms are known for their burrowing habits and their ability to dig tunnels through soil, which they use for digging out food from the ground. They play an important role in nutrient cycling and soil health by breaking down organic matter and releasing nutrients into the soil. The specific species of earthworms can vary greatly depending on their habitat and diet.
