Question

Unlike most mites, termites can digest wood. This ability comes from protozoa that live in the a termite’s digestive tract. These protozoa produce enzymes that digest wood, and they receive shelter and additional nutrients from the termites. The interaction between termite and protozoan is called A) commensalism. B) mutualism. C) parasitism. Eliminate D) socialism.

Answer 1

This is called B. Mutualism. The termite and the wood-digesting protozoa both receive benefits from each other, and therefore are in a "mutual" relationship.
