This would depend entirely on where you live.
I live in the U.P. of Michigan, so mine would be something like this:
An animal species native to my community is the wolf. The wolf can eat animals as small rabbits and birds, all the way up to deer. It is very rare to see a wolf hunted and eaten by something else besides a human.
I cannot finish the rest of this question because I wasn't there for Part 1.
This depends entirely on where you live. If you live near an ocean, maybe you can do it on sea creatures. If you live in the desert, maybe you can do it on snakes. If you live in an arctic area, you could do it on polar bears. There are many combinations and a quick Google search can tell you what they eat and what eats them.
