Boreal owls range over a much larger area than do other owls of similar size. The reason for this behavior is probably that the
small mammals on which owls feed are especially scarce in the forests where boreal owls live, and the relative scarcity of prey requires the owls to range more extensively to find sufficient food. Which of the following ,if true, most helps to confirm the explanation above?(A) Some boreal owls range over an area eight times larger than the area over which any other owl of similar size ranges.(B) Boreal owls range over larger areas in regions where food of the sort eaten by small mammals is sparse than they do in regions where such food is abundant(C) After their young hatch, boreal owls must hunt more often than before in order to feed both themselves and their newly hatched young.(D) Sometimes individual boreal owls hunt near a single location for many weeks at a time and do not range rather than a few hundred yards.(E) The boreal owl requires less food, relative to its weight, than is required by members of other owl species.
(B) Boreal owls range over larger areas in regions where food of the sort eaten by small mammals is sparse than they do in regions where such food is abundant
Explanation:
Living beings exhibit various changes in the behavior and niche to make themselves better fitted to the conditions of their habitats.
Boreal owls feed on the other smaller mammals such as mice and shrews. These organisms that serve as their prey are relatively less abundant in the habitat. To ensure the food availability, the boreal owls occupy a larger area so that they can catch their less abundant food organisms.
In the habitats where the prey species of boreal owls are present in a larger number, these owls occupy smaller regions since the food organisms are easily available.
