Question

Quizplus · Accepted Answer

Random dispersion occurs when individuals are distributed nearly uniformly throughout an area. Habitat conditions and resource availability do not have a strong influence on the pattern of dispersion, and individuals do not attract or avoid one another. Choice A is incorrect because random dispersion is not associated with scarce resource availability or attraction/avoidance behavior. Choice B is incorrect because clumped dispersion is associated with fairly steady resource availability. Choice C is incorrect because nearly uniform dispersion is not associated with random resource availability or lack of attraction/avoidance behavior. Choice E is incorrect because clumped dispersion is not associated with scarce resource availability AND attraction/avoidance behavior.
