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.
A population that did not grow in close relation to the amount of resources available in the environment, and dramatically overshot the carrying capacity, would experience:
A. logistic growth, such as shown on the S-shaped curve
B. exponential growth, such as shown on the J-shaped curve
C. unpredictable growth, such as shown on the ?-shaped curve
D. exponential growth, such as shown on the S-shaped curve

However, population growth for humans has exhibited exponential growth for over the last 350 years (since the Industrial Revolution). Which of the following can explain this phenomenon?
