It may involve the interchange of resources, for example food, shelter, and nutrients or may interchange services like transportation, and protection.

Termites are mutualistic related to protozoa which lives inside the insects gut. Termite gets benefits from the bacterial symbiont ability which is present in the protozoa to digest the cellulose.
