There is a cycle of life among animals. To survive, one animal becomes prey for another. That means that their life is in danger. A wolf may eat a smaller animal to stay. First, the wolf must attack the animal. Animals do this to live. It is the instinct for them to live. The animals who are victims to the other animals are known as the prey. These animals, who are the prey, are probably predators of smaller animals. However, these animals may eat other smaller animals or insects that pose a problem.
