AP Understanding Population Dynamics and Density

What could cause exponential growth in population in a community?

• people lifting heavy stuff

• a community leaving

• someone spreading a plague

• people moving to the community/unlimited resources

At what population was carrying capacity met?

• 250

• 1000

• 400

• 720

What pattern of population distribution does this school of fish represent?

• Random

• Uniform

• Clumped

• Knotted

What is the carrying capacity of an environment?

• The maximum number of individuals an environment can support indefinitely without degradation.

• The total number of species in an ecosystem.

• The average number of offspring produced by a species.

• The minimum population size needed for a species to survive.

Which of the following is a factor that can affect population growth?

• Climate change

• Birth rate

• Immigration policies

• All of the above

How does immigration impact population density?

• It decreases population density by spreading people out.

• It increases population density by adding more people to a given area.

• It has no effect on population density.

• It only affects population density in rural areas.

Which of the following best describes a clumped population distribution pattern?

• Individuals are evenly spaced throughout an area.

• Individuals are randomly distributed without a predictable pattern.

• Individuals are grouped in patches or clusters.

• Individuals are distributed in a linear pattern.

What is the effect of a high birth rate on population growth?

• It leads to a decrease in population growth.

• It has no effect on population growth.

• It contributes to an increase in population growth.

• It stabilizes population growth.

Which of the following equations represents exponential population growth?

What is a potential consequence of exceeding the carrying capacity of an environment?

• Increased biodiversity

• Resource depletion and environmental degradation

• Stabilization of population size

• Improved living conditions for all species
