During exponential growth, a population always
a. Has a constant per capita population growth rate
b. Quickly reaches its carrying capacity
c. Cycles through time
d. Loses some individuals to emigration

According to the logistic growth equation

$\frac{dN}{dt}=rN\frac{(K-N)}{K}$

a. The number of individuals added per unit time is greatest when N is close to zero.

b. The per capita population growth rate increases as N approaches K.

c. Population growth is zero when N equals K.

d. The population grows exponentially when K is small.

Which of the following represents a demographic transition?

a. A population switches from exponential to logistic growth

b. A population reaches a fertility rate of zero

c. There are equal numbers of individuals in all age groups

d. A population switches from high birth and death rates to low birth and death rates

Explain why biologists want to maintain (a) 'habitat corridors' that connect populations in a metapopulation, and (b) unoccupied habitat that is appropriate for the species in question.

Populations that rely on stored resources are likely to overshoot the carrying capacity of the environment and consequently experience a(n).

a. Demographic momentum

b. Cultural carrying capacity

c. Decrease in death rates

d. Population crash

e. Exponential growth

Skyrocketing growth of the human population appears to be mainly a result of

a. A drop in death rate due to sanitation and health care

b. Better nutrition boosting the birth rate

c. The concentration of humans in cities

d. Social changes that make it desirable to have more children

Indicate what is correct and incorrect about this statement: If lizards want to survive during climate change, they can evolve new life-history traits.

The current carrying capacity of Earth for the human population may have been inflated by

a. Demographic momentum

b. The tendency for women to want to control family size

c. An artificially low number of density-independent factors

d. Our use of fossil fuels

e. Recent population crashes

Which of the following statements about human populations in industrialized countries is correct?
