Which reflects positive density-dependent population regulation?
I. Small populations of flowers produce fewer seeds per individual than large populations of flowers.
II. Large groups of birds are better able to detect and avoid predators than small groups of birds.
III. The probability that a squirrel will be killed by a forest predator does not depend on the size of the squirrel population.

Question

Quizplus · Accepted Answer

Positive density-dependent population regulation occurs when the fitness or survival of individuals increases with population density. Both I and II describe scenarios where individuals benefit from being in larger groups, either through increased reproductive success or enhanced predator detection.
