In this module, we examined population growth models, which help us understand population increases and decreases. Exponential growth models are the simplest because they assume unlimited resources. Logistic growth models are more realistic because they incorporate a carrying capacity and the associated density-
Module 19 AP® Review Questions
1. The intrinsic growth rate of a population
occurs at the population’s carrying capacity.
depends on the limiting resources of the population.
increases as the population size increases.
only occurs under ideal conditions.
decreases as the population size increases.
2. Population growth using the exponential growth model
increases at a constant rate.
applies to most populations only after a long time.
has an increasing intrinsic growth rate.
represents ideal conditions that rarely occur in natural populations.
incorporates the carrying capacity of the population.
3. An r-selected species characteristically has
a type I survivorship curve.
few offspring.
a population near carrying capacity.
significant parental care.
a fast population growth rate.
4. Which is true of a population overshoot?
It occurs when reproduction quickly responds to changes in food supply.
It is followed by a die-
It is most likely to be experienced by K-selected species.
It rarely occurs in species with type III survivorship curves.
It occurs when a species stops growing after reaching the carrying capacity.
5. Inbreeding depression
rarely occurs in highly connected metapopulations.
results from the creation of corridors between populations.
results in increased rates of reproduction.
occurs in species that are experiencing overshoot.
rarely occurs in K-selected species.
