Tiny arachnids, also known as mites (5 letters), are small arthropods that belong to the class Arachnida. They are usually less than 1 millimeter in size and can be found in a variety of habitats, including soil, water, and plants. Mites are known to feed on organic matter, such as fungi, bacteria, and other small organisms. They are also important in the food chain, as they are a source of food for many animals.
