The relationship between a termite and the protozoa in its intestine is described as symbiosis. Symbiosis is a type of interaction between two different species that live together in a close and mutually beneficial relationship. In the case of termites and protozoa, the termite provides a suitable environment for the protozoa to live in, while the protozoa help to digest the cellulose in the wood that termites eat. This mutualistic relationship benefits both the termite and the protozoa, and neither of them would be able to survive without the other.
