Key deer, a subspecies of white-tailed deer, are only found on a few islands in the Florida Keys. They are tiny deer that weigh
45 to 65 pounds, which is very small compared to the 130- to 300-pound white-tailed deer that are found on the North American mainland. Which of the following conditions most likely resulted in the small size of the Key deer? a. Human influence caused increases in Key deer populations that improved genetic variation.
b. Limited food and water resources favored the survival of smaller deer.
c. Limited size variations of deer that migrated to the islands resulted in smaller deer.
d. Overproduction of offspring on the mainland led to migration of small, less successful deer to the islands.
A: That answer is illogical at best B: It makes sense, the smaller you are, the less food you need C: This would need extensive studying of key deer ancestry to figure out D: This could work over thousands of years. But an overpopulation of one wouldn't push out the other. Ungulates (hooved mammals) of different species often work together.
"Limited food and water resources favored the survival of smaller deer" is the one condition among the following choices given in the question that most likely resulted in the small size of the Key deer. The correct option among all the options that are given in the question is the second option or option "b".
An area's carrying capacity is not static. The carrying capacity may be lowered by resource destruction and degradation during an overshoot period or extended through technological and social changes.
A single fundamental similarity and or unity among all living organisms, is that all living organisms are composed of the basic units is life known as cells.
