Carrion, the dead remains of animals, is removed by scavengers and insects.
Carrion is the dead and decaying remains of an animal. Carrion, though repugnant to humans, is an important source of food for various other animals and insects that feed on it and aid in the decomposition process. Scavengers like vultures and hyenas are attracted to animals that are already dead. The type of carrion with which the majority of us in Western culture are the most familiar is road kill - animals killed on roads by automobiles and left to decay in the open.
