Because they've all been eaten.

Another Answer:

Looking at the Food Chain as a Competitive Pyramid, the higher you go, the more competitive the species, i.e. less likely to exist peacefully with peer species competition, due to distribution of resources. From a predatory diet standpoint, it takes a certain number of prey to sustain 1 predator, a certain number of that predator species to support a predator on the next tier up, and so forth.
