Humans need oxygen to breathe. Plants produce oxygen. How do places (like a desert) with no plants for miles on miles have any life or oxygen?

Question

Title says it all. Just curious as to how there is anything living if there is no plants to give off oxygen. Does other stuff give off oxygen? Is there just enough on the planet in general for it to flow everywhere?
