In an association of two animal species, one is a termite which feeds on wood and the other is a protozoan Trichonympha present in the gut of the termite. What type of association do they establish?
Termite and Trichonympha show mutualism; a relationship in which both the organisms are benefited from each other. Trichonympha breaks down cellulose in the wood and thus help the termite in the digestion of wood. Trichonympha also feeds on fragments of wood.
