All humans eat different things. Some eat lima beans, spinach, broccoli, or turnip greens.
Some humans eat hamburgers, hotdogs, potato chips, or pork sausage.
The list of what humans eat could take hundreds of pages to write. It is the same with grasshoppers. Grasshoppers are members of the biological order known as Orthoptera. This group includes crickets, katydids, cockroaches, and thousands of other insects. Each group eats something different.
