The termite gut protist, Mixotricha paradoxa, has at least two kinds of bacteria attached to its outer surface. One kind is a spirochete that propels its host through the termite gut.

Which term(s) is (are) applicable to the relationship between the two kinds of bacteria?
1.    mutualism
2.    parasitism
3.    symbiosis
