A parasite that lives on the external parts of its host is known as what?

Explanation:
Living on the outside of the host is an external parasite, or ectoparasite. These organisms attach to the skin, hair, or feathers and feed on blood or skin secretions without entering the body. This is different from endoparasites, which live inside the host’s body, such as in the intestines or tissues. Viruses and bacteria are types of microorganisms that cause infections, but the term here specifically describes parasites that reside on the surface of the host, like ticks, fleas, or lice.
