Population Ecology Pulse Check

What is population growth?

• Decrease in the number of individuals in a population over time.

• The average number of individuals in a population.

• The movement of individuals from one population to another.

• Increase in the number of individuals in a population over time.

Define carrying capacity.

• maximum number of individuals of a species that an environment can support sustainably

• the maximum number of individuals of a species that an environment cannot support sustainably

• the average number of individuals of a species that an environment can support sustainably

• the minimum number of individuals of a species that an environment can support sustainably

What are density-dependent factors?

• Factors that affect the size or growth of a population in relation to its temperature.

• Factors that affect the size or growth of a population in relation to its geographical location.

• Factors that affect the size or growth of a population in relation to its genetic makeup.

• Factors that affect the size or growth of a population in relation to its density.

Give an example of a density-dependent factor.

• Competition for resources

• Climate change

• Predation

• Genetic mutation

What are density-independent factors?

• Environmental factors that have no impact on a population's size or density.

• Environmental factors that only affect a population when its size or density is low.

• Environmental factors that affect a population regardless of its size or density.

• Environmental factors that only affect a population when its size or density is high.

Provide an example of a density-independent factor.

• Predator-prey relationship

• Climate change

• Competition for resources

• Natural disaster

What is population distribution?

• Pattern of where people live within a given area or region.

• The average age of people in a given area or region.

• The number of people in a given area or region.

• The number of males and females in a given area or region.

Explain the concept of uniform distribution in population ecology.

• Individuals are randomly distributed throughout a habitat with no specific pattern.

• Individuals are evenly spaced throughout a habitat or area when resources are abundant and evenly distributed, and there is no competition or territorial behavior among individuals.

• Individuals are evenly spaced throughout a habitat due to competition for resources.

• Individuals are evenly spaced throughout a habitat due to territorial behavior.

Describe the concept of random distribution in population ecology.

• Pattern of individuals being distributed randomly throughout a habitat or area

• Pattern of individuals being distributed in a linear manner throughout a habitat or area

• Pattern of individuals being distributed in a clustered manner throughout a habitat or area

• Pattern of individuals being distributed evenly throughout a habitat or area

What is clumped distribution in population ecology?

• Individuals are grouped together in patches or clusters within a population.

• Individuals are spaced out in a regular pattern within a population.

• Individuals are randomly distributed within a population.

• Individuals are evenly distributed throughout a population.
