A species of bat nearly went extinct due to the destruction of its forest habitat. However, conservationists preserved a small remnant population of the species in a large forested reserve. The population grew and it appeared that the species would rebound when a disease suddenly wiped out the entire population. What is the likely primary reason for why this occurred? I. the low genetic diversity of the population II. the reduced ecosystem diversity of the forest III. greater contact with humans, who passed on the disease * 4 points I only II only III only I and II
