Worms are elongated, soft-bodied invertebrates that belong to various phyla, with the most common being Annelida, Nematoda, and Platyhelminthes. They play crucial roles in ecosystems, such as decomposing organic matter and aerating the soil, which benefits plant growth. There are many types of worms, including earthworms, which are vital for soil health, and parasitic worms, which can affect the health of animals and humans. Despite their simple structure, worms exhibit fascinating behaviors and adaptations that allow them to thrive in diverse environments, from gardens to oceans.
