a.
The population growth rate will not change
b.
The population growth rate will approach zero
c.

d.
The carrying capacity of the environment will increase
The carrying capacity (K) is the maximum population size that can be supported or sustained by a given environment. Which of the following statements about the carrying capacity is NOT true?
Select one:
a. We can think of K as some "average" value that a given environment can support.
b. Environmental fluctuations cause the carrying capacity to fluctuate over time.
c. Once a population reaches its carrying capacity, the size of the population remains constant.
d. When a population overshoots K, individuals die due to lack of resources.
