Here's why:
* Predators and Prey: The African Savannah is a complex ecosystem with a food web. While some animals are predators and eat other animals (lions, cheetahs, leopards, etc.), others are prey animals (zebras, gazelles, wildebeest, etc.). There are also herbivores that only eat plants.
* Scavengers: Some animals, like hyenas and vultures, are scavengers. They eat the carcasses of dead animals, which helps to keep the ecosystem clean.
* Plant Eaters: Many animals are herbivores, consuming only plants, such as elephants, giraffes, and various antelope species.
Therefore, while there's a lot of predation in the African Savannah, not every animal is on the menu.
