Population Growth and Limiting Factors Quiz

What factors contribute to changes in population size?

• Births, deaths, immigration, and emigration

• Only births and deaths

• Only immigration and emigration

• None of the above

How is population growth different from population growth rate?

• Population growth measures size change, while growth rate measures the speed of change.

• Population growth measures the speed of change, while growth rate measures the size change.

• Neither measures any aspect of population change.

• Both measure the same aspect of population change.

Which of the following is an abiotic factor affecting population size?

• Predation

• Infection

• Competition

• Temperature

What does it mean when a factor is density-independent?

• It affects populations based on their density.

• It only affects low-density populations.

• It only affects high-density populations.

• It affects populations regardless of their density.

Which of the following is a biotic factor that can limit population size?

• Salinity

• Predation

• Water

• Sunlight

How does competition affect population size?

• It has no effect on population size.

• It only affects abiotic factors.

• It decreases population size by limiting resources.

• It increases population size by providing more resources.

What happens to prey numbers if predator numbers increase?

• Prey numbers decrease.

• Prey numbers remain the same.

• Prey numbers increase.

• Prey numbers fluctuate randomly.

What is the competitive exclusion principle?

• Two species can share the same niche indefinitely.

• No two species can occupy the same niche for a long time.

• Species can only coexist if they have the same resources.

• Species can only coexist if they are in different environments.

How do species coexist in the same environment according to resource partitioning?

• By migrating to different areas

• By avoiding each other completely

• By sharing resources and occupying different niches

• By competing for the same resources

What is an example of resource partitioning in a tree?

• All species living at the top of the tree

• Different species living in different parts of the tree

• Species avoiding the tree entirely

• All species living at the bottom of the tree
