When we talk about a carcass, we usually mean the remains of a dead animal, like a cow or a deer. In everyday conversation, people might use this word when they're talking about hunting or farming. For example, if you go on a hunting trip and kill a rabbit, its body is called a carcass. You might then take it to a butcher to be cut up for meat. Some people also use the word "carcass" in a more general sense, like when they're talking about animal remains that are left behind after a natural disaster.
