🤓 Based on our data, we think this question is relevant for Professor Spilios' class at BU.

Solution: Elephants are not the most common species in African grasslands. 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. Elephants can be defined as what type of species in this community? a. keystone b. redundant c. dominant d. dominant and keystone
