The clownfish is a species of fish that lives between the stinging tentacles of sea anemones. the clownfish protects the anemone from anemone eating fish, while the anemone’s tentacles protect the clownfish from predators. the relationship between clownfish and anemone is an example of

mutualism

Explanation:

Mutualism is a type of symbiotic relationship between two organisms in which both benefit and neither is affected negatively in any way.

Mutualism can be in the form of resource-resource when it involves an exchange of resources between the organisms, service-resource when a resource is being swapped for a service or, service to service when it involves exchange of services between the two organisms.

In this case, the clownfish offers protection service to the sea anemone while the sea anemone in turn also offers protection to the clownfish. This is a service-service mutualism.
