Wolves roamed large areas in the western United States until humans eliminated them in the early 1900s. Without wolves as predators,
herbivore populations grew and overgrazed the land. To bring back biodiversity in Yellowstone National Park, scientists reintroduced wolves
in 1995,
Which result would provide evidence that the reintroduction of wolves restored biodiversity in the park?
O A elk populations increasing after scientists introduced the wolves into the park
OB. wolves consuming populations of elk and reducing the population to its original size within the park
O c the wolf population declining because they consumed more elk than the park could naturally sustain
O D. elk consuming large areas of newly established trees that grow in open areas after the introduction of wolves
