A tapeworm lives inside the intestines of a pig, robbing the pig of nutrients it needs.
Explanation:
Parasitism is the association between two organisms wherein parasite lives in or on the surface of the body of the host organism and derives nutrition from it. Here, the parasite is benefited while the host organism is harmed.
