Question

a relationship between two species in which one species, the parasite, benefits from the other species, the host, which is harmed

Explanation:

Parasitism is a biological relationship where one organism (parasite) benefits at the expense of another (host). Hunting is about one organism actively seeking and killing another for food. Symbiosis is a broader term for close relationships between different species (can include mutualism, commensalism, parasitism). Predation is when one organism (predator) kills and eats another (prey). The description in the question specifically matches the definition of parasitism as it emphasizes one species (parasite) benefiting while the other (host) is harmed.

Answer:

parasitism
