The termite gut protist Mixotricha paradoxa has at least two kinds of bacteria attached to its outer surface.One bacterium is a spirochete that propels its protist 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 of the following terms is (are)applicable to the relationship between the two kinds of bacteria?
A)mutualism only
B)mutualism and parasitism only
C)parasitism and symbiosis only
D)mutualism,symbiosis,and metabolic cooperation
E)parasitism,symbiosis,and metabolic cooperation

The relationship between the two kinds of bacteria is an example of mutualism because both benefit from each other's presence. It is also an example of symbiosis because the bacteria are living in close association with each other. Additionally, there is metabolic cooperation between the bacteria, as one synthesizes ATP that is used by the other to provide locomotion.
