A carnivore at the top of it's food chain is called an "apex" predator.
Carnivores are meat eaters right?
Yes, carnivores are animals that depend only on animal flesh for their energy requirements!
Ok and herbivores are vegetable consumers
Correct, in fact herbivores have adapted to their diets with teeth good for rasping or grinding their food.
Amazing! I wonder what kind of teeth carnivores must have to handle tearing meat?
They must be sharp because their teeth are good for hunting and defensive purposes. 
I don't know much about carnivores what else can you tell me?
The word "carnivore" doesn't always refer to the mammalian order Carnivora. Even though it seems like it would.
Really? then what is it referring to?
