Which of the following is an incorrect statement about the regulation of populations?

A) The logistic equation reflects the effect of density independent factors, which can ultimately stabilize populations around the carrying capacity.

B) Density-independent factors have an increasingly greater effect as a population’s density increases.

C) High densities in a population may cause physiological changes that inhibit reproduction.

D) Because of the overlapping nature of population-regulating factors, it is often difficult to precisely determine their cause-and-effect relationships.
