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. A second type of bacteria synthesizes ATP, some of which is used by the spirochetes. The locomotion provided by the spirochetes introduces the ATP-producing bacteria to new food sources. Which term(s)is (are)applicable to the relationship between the two kinds of bacteria?
1)mutualism
2)parasitism
3)symbiosis
4)metabolic cooperation
A) 1 only
B) 1 and 2
C) 2 and 3
D) 1, 3, and 4
E) 2, 3, and 4

- Mutualism is present because both types of bacteria are benefitting from the relationship.
- Symbiosis is present because both types of bacteria are living in close association with each other and the protist.
- Metabolic cooperation is present because the ATP-producing bacteria are providing energy to the spirochetes, which helps them propel the protist through the termite gut.
