e next time you eat a salad, you may look at toes a little differently. you may see them as a sweet but now you know they can also be fierce warriors in garden.

Explanation:

The first blank is filled with "destroy" as the text mentions caterpillars can destroy crops (which implies harming in a way that affects large numbers). For the second blank, the text says "When this tomato plant releases a repellent chemical...", and from the context of the plant's defense mechanism when a caterpillar is present (the action related to the caterpillar's presence that triggers the plant's response), "moves" is the appropriate choice as it's a common action associated with a caterpillar being on the plant (and the plant sensing its presence).

Answer:

destroy; moves
