You DO realise that populations numbers swing wildly, reacting to the changes in weather, climate, soil, and other environmental factors, right?
There IS no such thing as a stable, balanced population over any given period of time.
If there is more prey, there will be more predators, because more of their offspring survive. If the numbers of prey go down, so do the predators, as they and their offspring are weaker or starve outright.

Well, it could go much worse if nature were uncontrolled. For example, a disease that happens to target mostly prey species or a disaster near predator areas- there's nothing to prevent the earth's organisms from going right out of the balance if nature and natural selection is not carefully guided by an intelligent being.
