Hi there!
Cheetahs survive many different ways, as people do.
For a start, cheetahs need food, water, and oxygen to live. They can hide from threatening animals/hunters, too.
Unfortunately, there aren't many cheetahs left in the wild, due to habitat destruction and overhunting.
Did you know...
Cheetahs wouldn't be endangered and would be at a steady population rate if natural causes made them die - Not humans.
But, anyway, back to the topic: Cheetahs can survive a little more by hiding from humans and moving to habitats that didn't get cut down and taken away from them.
Hope this helps! :D
