    • Do lions really dominate African wildlife?

      Q: Do lions really dominate African wildlife?

      A: Because lions only inhabit certain limited parts of Africa, which is a very large continent with varied geology, they cannot accurately be said to dominate wildlife on that continent, though they are apex predators who tend to be at or near the top of their ecosystem's food chain. And while lions are skilled hunters and fierce predators, some other predators, such as hyenas, have been known to outcompete and even dominate lions.
