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.
A tapeworm is endo-parasite of pig and lives in its intestine. The worm feeds on the digested food present in the intestine of pig and thereby reduces the nutrients supply for the pig. Since the worm is benefited while the pig is harmed, it is an example of parasitism.
