Answer 1

The activity of animals that helps prevent grasslands from changing into forests is:

C. Buffalo trample tree seedlings with their pounding hooves.

By trampling tree seedlings, buffalo and other large herbivores help maintain the grassland ecosystem by preventing the establishment and growth of trees, which could otherwise lead to a gradual transformation of the grassland into a forested area.
