In the animal world, each kind of animal is a potential food for other kinds of animals. When an animal observes another animal entering its field of vision, it decides whether to attack, stay still, or run away. Choosing to attack can make the opponent your own food. If you choose to stay where you are, you can wait and see, but you may miss the opportunity to attack or escape. Escape is the safest strategy, but if the other person is not dangerous, escape is not necessary. If the other person is weak, choose to run away, you will lose the chance to get food.
