Question: The vicuña is a camel relative found in the Andes of South America. Suppose that food is exceptionally abundant for several years, resulting in an increase in vicuña population density. This increase in vicuña population density allows pumas, one of the main predators of vicuñas, to find their prey more easily. Polar bear numbers have been declining over the last decade due to a loss of sea ice on which to hunt seals. The loss of sea ice results in more territorial confrontations between polar bears and the inability of some female bears to feed their cubs. Coral reefs are comprised of large numbers of individual corals, which are small animals related to jelly fish. Abnormally high water temperatures in the Caribbean in 2005 resulted in a massive coral bleaching event. Many of the corals subsequently died. Is the increased predation on the vicuña population density-dependent or density-independent? density-independent density-dependent Is the increase in territorial confrontations among polar bears density-dependent or density-independent? " Was the bleaching event density-dependent or density-independent? "
