Living organisms like mountain lions need resources from the environment to survive and reproduce, including energy sources, space to live, and mates. Mountain lions are carnivorous predators that eat primary consumers like deer, rabbits, and bighorn sheep. They also eat opossums, raccoons, skunks, and coyotes. Mountain lions usually hunt at night and silently stalk or hunt prey from behind. Mountain lions are found in many different types of ecosystems across North America and can make their home anywhere there is shelter and prey.
