What is an "earthworm"?
An earthworm is a terrestrial annelid worm belonging to the family Lumbricidae. It has a long, cylindrical body divided into segments. Earthworms are essential for soil health and fertility as they tunnel through the soil, improving its structure and nutrient content. They feed on organic matter, breaking it down and facilitating decomposition. Earthworms also play a vital role in soil aeration and water infiltration, benefiting plant growth. Due to their ecological significance, earthworms are considered valuable indicators of soil health and are widely studied by scientists and ecologists.
