What type of interaction benefits both species involved?

Mutualism is a type of interaction where both species involved benefit from the relationship. This can occur in various forms, such as when one organism provides food, while the other offers protection or other services. Examples of mutualism include bees pollinating flowers while obtaining nectar or cleaner fish removing parasites from larger fish in exchange for food.

In this relationship, the interactions are essential for the survival or reproduction of both species, illustrating how cooperation in nature can lead to a win-win situation. This contrasts with the other types of interactions mentioned, where at least one species does not derive benefits or may even be harmed in the relationship.
