Question

Does the success of a prey population depend on its predators? Explain.

Answer 1

Yes very much so. Let's say the prey were snakes. The predators were birds. If many of the birds were wiped out, there are barely any limiting factors maintaining the snake population. The snake population can overpopulate and affect other species. If there were an abundance of birds, the snake population would decrease immensely, but then the bird population will soon run out of snakes and starve. This will then cause the bird population to suffer. As you can tell, both the prey and predator population effect each other immensely. 

Answer 2

Answer:yes it does like the mouse and shrew bones were common to all three owls so they were not useful in identifying environments. The gopher bones were unique to the great grey owl of Alaska. Gophers are rodents that are successful in areas with soft soil and lots of grass, so the gopher and this owl would be found in the meadows and evergreen forests of Alaska. The bat was unique to the barking owl of Australia. The bat would be found in woodland habitats where there are many trees the bat can hang from. The gull bones were unique to the short-eared owl of Cuba. Gulls are wetland birds, so the gull and this owl would be found in marshes and coastal areas.
