animals in the african savanna depend on other animals in their ecosystem to survive.
the african savanna is home to scavengers, which survive off the remnants left by predators.
the warm climate of the african savanna makes food plentiful for all animals.

Explanation:

The details mention vultures (scavengers) depending on large predators' leftovers, elephants making vegetation edible for smaller herbivores (showing one animal's action benefits another), and lions (predators) feeding on herbivores. The first option "Animals in the African savanna depend on other animals in their ecosystem to survive" encompasses all these inter - animal dependencies. The second option only focuses on scavengers and predators' leftovers, missing the elephant - smaller herbivore relationship. The third option about the warm climate is not related to the animal - to - animal dependency details provided.

Answer:

Animals in the African savanna depend on other animals in their ecosystem to survive.
