In models of logistic population growth,

a. the population growth rate slows dramatically as N approaches K.
b. only density-dependent factors affect the rate of population growth.
c. new individuals are added to the population as N approaches K.
d. carrying capacity is never reached.

a. the population growth rate slows dramatically as N approaches K.

Explanation:

The population growth rate refers to the change in number of individuals in a population over time. In logistic growth, the growth rate of the population per capita tends to get smaller as population size approaches the carrying capacity. The carrying capacity is the maximum population size that can be sustained by the limited resources in the environment.

answer; i believe that the correct answer is rapid and subsequently slow down;

yes, since there is a positive and a negetive if the positive and negitive wasn't there wouldn't a flow electricity in it.
