<human>:  Why do chimpanzees hunt?
<bot>: Chimpanzees hunt for a variety of reasons. They hunt for food, to defend themselves, and to mate. Chimpanzees are omnivores and eat a wide variety of foods, including fruits, leaves, nuts, and insects. Chimpanzees also hunt to protect themselves from predators such as leopards and other large animals. In addition, chimpanzees hunt to mate with females. Males are more likely to mate with females that have hunted successfully, and so hunting is an important part of the mating process.
