Earthworm

Earthworms are segmented invertebrates that live in the soil, playing a vital role in maintaining healthy ecosystems. They burrow through the ground, creating tunnels that improve soil aeration and facilitate water drainage. As they consume organic matter like dead leaves and plant material, earthworms break down organic material, enriching the soil with nutrients. Their activity promotes fertility and supports plant growth. Earthworms have a simple body structure with segments, a set of muscles, a digestive system, and a simple nervous system. They are important contributors to soil health, making them key players in natural nutrient cycling and sustainable agriculture.
