A predator species is one that kills and eats other organisms for food.
A predator species is one that kills and eats other organisms for food. Nonpredator species may still consume other organisms - for example, scavengers feed off dead animals and parasites feed off their hosts - but by definition predators capture and kill live prey. A predator species can also be prey - for example, sardines may prey on phytoplankton, but are themselves hunted by dolphins and sharks.
