In mutualism, both species involved in the relationship gain benefits that contribute to their survival and reproduction. This symbiotic interaction can take many forms, such as pollinators like bees benefiting from the nectar of flowers while simultaneously aiding the plants in reproduction by transferring pollen. Another example is certain types of fish that clean parasites off larger fish; the cleaner fish receive food while the larger fish benefit from being rid of harmful parasites. This synergistic interaction enhances the fitness of both organisms, making mutualism an important ecological relationship in various ecosystems.
