The type of interaction where both species benefit is called mutualism.

Here are some examples:

* Bees and flowers: Bees get nectar from flowers, which they use for food. In the process, they pollinate the flowers, allowing them to reproduce.

* Cleaner fish and larger fish: Cleaner fish eat parasites off larger fish, providing them with food and keeping the larger fish healthy.

* Oxpeckers and zebras: Oxpeckers eat ticks and other parasites off zebras, providing them with food and keeping the zebras clean.

* Mycorrhizae fungi and plants: Mycorrhizae fungi live in the roots of plants, helping them to absorb nutrients and water. In return, the fungi receive sugars from the plants.

In all of these examples, both species involved benefit from the interaction, making it a mutualistic relationship.
