Question 2

The orangutans found in Borneo tend to lead a solitary existence because they have to forage far and wide for sufficient food.

  a. orangutans in Sumatra tend to be heavier because they don't have to search so hard for food.
  b. a solitary existence is a function of habitat productivity.
  c. habitat productivity promotes harmony.
  d. gregariousness is a function of habitat productivity.
