Transcript
NARRATOR: The grasshopper is well equipped to gather its food, which consists primarily of green plants. Its strong mouthparts—the mandibles—are adapted to biting and chewing tough plant tissue; the palps are used to grasp the food.
In summer a field or meadow may swarm with thousands of grasshoppers feeding on the green plants. Though a single grasshopper may eat relatively little, great numbers can strip a farmer's field bare, thus endangering human food supply.
