Most people say it is sad or simply a part of nature when an animal is eating another animal. Omnivores and carnivores like humans, dogs, and lions all eat other animals as a source of food.
Without knowing what type of animal 'he' is it is hard to say. Any animal not eating is not a good sign though and it would be best to seek professional veterinary advice for your animal.
The one eating is called consumer. The organism killing and eating another is called a predator. The other animal is prey.

Animal cannibalism.
Like any other animal, from eating it and digesting it.
A carnivore is an animal that eats other animals. A lion (carnivore) eating a zebra (herbivore) is one example.
It is the prey. The animal doing the eating is the predator.
If a labrador stops eating, like ANY other animal who stop consuming nutrients...IT WILL DIE. Have a nice day :)

Depends on the animal and depends on how big a piece they devoured. A carnivorous/omnivorous animal like a dog won't die after eating leather; same with a wolf or a coyote or cougar or bear. A herbivorous animal may not either but it's hard to say.
The waste product produced from the animal eating grasses and other food stuffs.
Any carnivore, a carnivore is a meat eating animal.
