Which of the following statements about the logistic growth model is accurate?
I. The per capita rate of population increase declines as population size increases.
II. The overall rate of population increase is highest at K/2.
III. The overall rate of population growth is negative when N is greater than K/2.

I is true because the logistic growth model includes a carrying capacity (K), which is the maximum population size that can be sustained in a given environment. As the population size approaches K, the per capita rate of population increase declines.

II is also true because the overall rate of population increase is highest at N=K/2, which is the point at which population growth is accelerating the fastest.

III is false because the logistic growth model predicts that population growth will be positive as long as N is less than K (i.e. the environment can still support more individuals).
