Self-thinning

Question

Self-thinning

Quizplus · Accepted Answer

Self-thinning is a density-dependent process that occurs when a population reaches high densities and leads to the death of smaller and weaker individuals, resulting in the remaining individuals having more space and resources to grow and survive. Therefore, option B is the correct choice as it accurately describes self-thinning. Option A is incorrect because self-thinning is observed in both mobile and sessile organisms. Option C is incorrect because self-thinning results in the death of some individuals and does not necessarily increase the survival rate of all individuals. Option D is incorrect because self-thinning is a type of contest competition, where organisms compete for limited resources, rather than scramble competition.
