Elephants are not the most dominant species in African grasslands, yet they influence community structure. The grasslands contain scattered woody plants, but they are kept in check by the uprooting activities of the elephants. Take away the elephants, and the grasslands convert to forests or to shrublands. The newly growing forests support fewer species than the previous grasslands. Which of the following describes why elephants are the keystone species in this scenario?
A) Essentially all of the other species depend on the presence of the elephants to maintain the community.
B) Grazing animals depend upon the elephants to convert forests to grassland.
C) Elephants prevent drought in African grasslands.
D) Elephants are the biggest herbivore in this community.
E) Elephants help other populations survive by keeping out many of the large African predators.

Elephants are large mammals especially elephants in Africa have a height of 4 meters and weigh up to 7 tons. In the elephant ecosystem has a very important role and has an impact on the environment. With a large size and height, other predatory animals do not want to get close to elephants. Moreover, this elephant is an animal that prefers to group. Perhaps very few elephants have fallen prey to predators. Thus elephants are animals that indirectly protect other animals in Africa. Things like this also indirectly make grasslands become more fertile and other animal species also become more numerous.
