The scavenger usually waits until the predator is gone to clean up and eat the remains also. Basically a predator feeds on living organisms, while the scavenger eats animals that are already dead. These two types of animals are very crucial to the ecological system. These animals don’t allow any source of food go to waste. These animals may be allies when eating their enemies. The predator never allows the scavenger to consume food, and it’s up to the scavenger to steal the meet while the predator did the long hard work.
