Earthworms help to fertilise the soil by bringing nutrients closer to the surface. Earthworms are widespread in Britain and Europe. They have been introduced to most parts of the world. They live in soil at depths of up to 2 metres and feed on decaying organic matter in the soil.
An earthworm is a soil -dwelling terrestrial invertebrate that belongs to the phylum Annelida. The term is the common name for the largest members of the class (or subclass, depending on the author) Oligochaeta.
Earthworms are a group of terrestrial annelids that constitute the suborder Lumbricina. They are characterized by an elongated, segmented body equipped with bristle-like hair for anchoring to soil. These animals have a nearly cosmopolitan distribution, found on all continents except Antarctica.
Earthworm, any one of more than 1,800 species of terrestrial worms of the class Oligochaeta (phylum Annelida)—in particular, members of the genus Lumbricus. Seventeen native species and 13 introduced species (from Europe) occur in the eastern United States, L. terrestris being the most common.
Earthworms are more than just fish bait. They are the main contributors to enriching and improving soil for plants, animals and even humans. Earthworms create tunnels in the soil by burrowing, which aerates the soil to allow air, water and nutrients to reach deep within the soil.
Earthworms are vital to soil health and to plants growing in it because they transport nutrients and minerals from below to the surface via their waste. An earthworm can eat up to a third of...
Earthworms are harmless, often beneficial residents of the soil. Earthworms breakdown dead and decaying organic matter into rich humus soil, thereby supporting plant growth. They also dig tiny channels and make holes that aerate soil and improve drainage. Earthworms don’t have lungs; they breathe through their skin.
