Mutualism is a type of symbiotic relationship where both organisms involved benefit from the interaction.

Here are some examples:

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

* Cleaner fish and larger fish: Cleaner fish eat parasites off larger fish, getting food and keeping the larger fish healthy.

* Oxpeckers and zebras: Oxpeckers eat ticks and other parasites off zebras, getting food while keeping the zebras free of pests.

It's important to note that not all give-and-take relationships are mutualistic. For example, a parasitic relationship benefits one organism at the expense of the other.
