Question

What is 'commensalism'?

Answer 1

In ecology, commensalism is a relationship between two species of organisms in which one species benefit from the relationship and the other species is unaffected by it. For example, anemonefish lives among the forest of tentacles of an anemone. Hence it is protected from predators not immune to the sting of the anemone. In this, the anemone is not benefitting and only the anemonefish is benefitting.
