The disappearance of grasshoppers would hurt the frogs more than snakes because frogs are higher up in the food chain and rely heavily on insects like grasshoppers for food. Grasshoppers are a primary food source for many species of frogs, and without them, the frogs would have to find other sources of food to survive.
On the other hand, snakes are lower on the food chain and can survive on a variety of prey items, including rodents, lizards, and other small animals. While snakes do eat grasshoppers, they are not their primary food source, and they can switch to other prey items if grasshoppers become scarce.
Therefore, if grasshoppers were to disappear, the frogs would suffer a greater impact because they would lose a significant source of food, whereas the snakes would be less affected as they can adapt to other food sources. This would have a ripple effect on the ecosystem, as a decrease in frog populations could also impact other species that depend on them for food or play a role in the ecosystem's balance.
