Nematodes, commonly known as roundworms, are a group of worms that make up the phylum Nematoda. With well over 15,000 species identified today, they can be found in different habitats ranging from terrestrial to marine environments Nematodes. Nematodes are microscopic worms that live in the soil. While there are many kinds that are beneficial, feeding on fungi, bacteria, and other organisms, some harmful nematodes feed on plants. These plant-parasitic nematodes damage root systems and reduce a plant's ability to get water and nutrients from the soil
