Earthworms

Earthworms are segmented worms found in soil and freshwater environments, playing a vital role in ecosystems. They help improve soil structure, aeration, and nutrient availability through their burrowing activities and by breaking down organic matter. Their bodies are covered in a slimy mucus, aiding in movement and moisture retention. Earthworms breathe through their skin and are most active in moist conditions. They reproduce through a process called mating, where two worms exchange sperm. As natural recyclers, they contribute significantly to soil health, making them essential for agriculture and biodiversity.
