What term describes the relationship between different species in which at least one benefits?

Explanation:
Symbiosis is the term for interactions between different species in which at least one partner benefits. This includes mutualism (both benefit), parasitism (one benefits, the other is harmed), and commensalism (one benefits, the other is unaffected). The question’s description fits this idea, since at least one species gains a benefit through the relationship. The other options don’t describe interspecific relationships: a trophic level is a position in a food chain, cancer is a disease, and cytoplasm is the contents inside a cell.
