Question

Quizplus · Accepted Answer

Keystone species are important species within an ecosystem whose presence or absence can significantly impact the overall structure and functioning of the ecosystem. Lions are considered a keystone species on the African savanna because they help regulate prey populations, which in turn affects plant populations, and also help control the spread of disease within their prey populations. Without lions, there could be negative consequences for the entire ecosystem.
