Question 3 Which of these statements about the regulation of populations is correct? 1 pts Density-dependent factors usually involve changes in the abiotic environment. ☐ Density-dependent factors change in intensity as a function of population size. Density-independent factors alter birth rates and death rates irrespective of the number of individuals in a population. The logistic equation is designed to see how density-dependent factors stabilize a population around carrying capacity. ☐ Changes in the abiotic environment can alter carrying capacity.
