Nematode

Nematodes, also known as roundworms, are tiny, thread-like worms found in soil, water, and as parasites in plants, animals, and humans. They have a smooth, cylindrical body, usually a few millimeters to several centimeters long. Many nematodes play important roles in ecosystems, such as decomposing organic matter, but some are harmful, causing diseases in plants and animals. They reproduce quickly and can survive in various environments, making them both ecologically significant and relevant in agriculture and medicine. Despite their small size, nematodes have a significant impact on health, farming, and the environment.
