Zombies on the Food Chain

Humans as you know are on the top of the food chain, but not because of our natural abilities, its cause of our technology's and our intelligence's. So when you take those things away from us the odds are against us. So lets go over the differences between humans and Zombies. Humans are intelligent, have and can use weapons/ technology, and Speed (average speed 12mph). Zombies, have no intelligence's, which makes them unable to use  our weapons/ technology, these are the main reasons humans are on top of the food chain, and on top of that Zombies are slow. This puts them way way down on the chain, the only thing Zombies have going for them is that to an animal they look like a human, this may deter them from attacking, but its only a matter of time before they start to figure it out that Zombies are slow and don't know how to defend themselves. Now what will be the Zombies main predators? Stray dogs,there are lots and lots of them all over the world, they can get very aggressive and are a formidable force. There have been lots of cases of stray dogs attacking humans, some have actually killed humans. Now if these dogs can kill someone with the intelligence to run and fight, what do you think they would do to Zombies (note that these dogs would only be interested in the recently turned Zombies, because dogs digestive systems can't handle decomposed flesh). The big predator for the long term Zombies would be vultures, they have the digestive system that can handle the Zombie flesh, and they'd have no problem tearing through flesh and muscle, rendering the Zombie immobile eventually. Another predator for them are insects, flies, maggots, ants, ect... We don't even think of these when talking about predators, but think about how many flies you swat away from you in just one day, Now think of a Zombie it doesn't have the intelligence to swat flies or not stand in ants and Zombies have open wounds that cant heal. This means flies and ants will lay eggs in a Zombies eyes and wounds. Once the eggs hatch into maggots they begin to eat and ants begin to make the zombie there home, making tunnels inside it. eventually eating  its eyes and blinding it, rendering it even more defenseless to other predators or getting in its brain and killing it. Oh an one last predator, Us we aren't going without a fight an even though Zombies pose a moral dilemma I have the utmost confidence in us as a strong species to over come and prevail.
