Nt= N0 t represents:a.geometric population growth.b.annual growth rate.c.exponential growth rate.d.logistic growth.e.none of the choices apply.
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.
Based on the equation for logistic population growth,
Logistic Growth
O A. new Individuals are added most rapidly at low population sizes.
This figure displays the equation for logistic population growth and
visualizes population growth as a function of time (number of
generations) as it approaches carrying capacity. N stands for
population size, K stands for carying capacity, and r stands for
intrinsic rate of increase.
O B. population growth never exceeds K.
C. growth rate decreases as N approaches K.
D. the population keeps growing when N equals K.
