Which is an example of a parasite?

1. Mildew

2. Scabies

3. Tinea Barbae

4. Tinea Capitis

The correct answer is: Scabies

Scabies is indeed an example of a parasite. It is caused by the Sarcoptes scabiei mite, which burrows into the skin and causes intense itching and discomfort. This mite lives on the skin of its host, feeding on skin cells, which exemplifies the parasitic relationship where one organism benefits at the expense of another. In contrast, mildew, tinea barbae, and tinea capitis are not classified as parasites. Mildew refers to a type of fungus that grows in damp environments and does not rely on a host for survival or nourishment. Tinea barbae and tinea capitis are fungal infections affecting the beard area and the scalp, respectively. These infections are caused by dermatophytes, which are a different category of organisms that thrive on keratin in skin, hair, and nails rather than living off a host like a parasite does.
