Studies of rough-skinned newts have documented their ability to produce toxins in defense against a predator attack. The common garter snake, a predator of rough-skinned newts, exhibits a resistance to the toxin produced by the newt. In response, newts have been observed to produce increasingly potent toxins, which in turn results in selection for snakes with even greater resistance to the toxin. What phrase best describes this interaction between rough-skinned newts and garter snakes?

"The common garter snake, a predator of rough-skinned newts, exhibits a resistance to the toxin produced by the newt."

Explanation:

The phrase "The common garter snake, a predator of rough-skinned newts, exhibits a resistance to the toxin produced by the newt" literally shows the relationship established between the common garter snake and the rough-skinned newts. This sentence shows that animals have a relationship of predatorism, since the common garter snake feeds on rough-skinned newts, since the snake is resistant to the toxins produced by the newts, managing to establish predatorism with efficiency.
