The relationship between cnidarians and dinoflagellate algae is termed as symbiotic, because both the animal host and the algae are benefiting from the association. It is a mutualistic interaction.Fungi have several mutualistic relationships with other organisms. In mutualism, both organisms benefit from the relationship. Two common mutualistic relationships involving fungi are mycorrhiza and lichen.Termites have a mutualistic relationship with protozoa that live in the insect's gut.
