Small objects are often referred to as mites, which is a five-letter word. Mites are tiny arthropods that belong to the Acari family and are found in many different habitats. They are usually less than 1 millimeter in size and can be found in soil, water, and even on plants and animals. Mites can cause damage to crops and can also be a nuisance to humans, as they can bite and cause skin irritation.
