What is a relationship in which one organism is helped and the other is harmed?

Commensalism is a symbiotic relationship in which one species benefits while the other species is not affected. Parasitism is a symbiotic relationship in which one species (the parasite) benefits while the other species (the host) is harmed.

When one organism benefit while the other is neither harmed nor affected?

Commensalism happens when one species lives with, on, or in another species, known as the host. The host species neither benefits nor is harmed from the relationship. In our imagined example, various species of barnacles attach themselves to the skin of whales.

What is it called when one organism lives off another?

When one organism lives off another at the other’s expense, it’s called “parasitism.” Either way, living together is what “symbiosis” is all about; the word came to us, via German and New Latin, from the Greek symbiōsis, meaning “state of living together.” “Symbiōsis,” in turn, traces to “symbios” (“living together”).
