Predators rarely kill and eat all available prey because:
predator and prey species often occupy the same trophic level in an ecosystem
prey species often lack protective mechanisms to deter being eaten
many predator and prey species have a commensalistic relationship
predator species often will switch its prey as one prey species becomes less abundant
