Analyze how a uniform dispersion pattern might benefit a population.

• It allows for better resource allocation.

• It increases competition for resources.

• It leads to random mating.

• It results in clumped resources.

Apply the concept of carrying capacity to predict what happens when a population exceeds it.

• The population will continue to grow.

• The population will stabilize at a new higher level.

• The population will decrease due to resource depletion.

• The population will remain unaffected.

Evaluate the effect of density-independent factors on a population.

• They cause population size to fluctuate around carrying capacity.

• They have no effect on population size.

• They cause sudden and unpredictable changes in population size.

• They stabilize population size.

Analyze the relationship between population density and the spread of disease.

• Higher density decreases disease spread.

• Higher density increases disease spread.

• Density has no effect on disease spread.

• Lower density increases disease spread.

Apply your understanding of dispersion patterns to determine which pattern is most likely in a forest of trees.

• Clumped

• Uniform

• Random

• Dispersed
