Populations Notes - EES

Multiple Choice

• Births and immigration increase population size, while deaths and emigration decrease it.

• Births and emigration increase population size, while deaths and immigration decrease it.

• Births and deaths increase population size, while immigration and emigration decrease it.

• Deaths and immigration increase population size, while births and emigration decrease it.

Multiple Choice

Which of the following best describes the difference between specialist and generalist species?

• Specialist species thrive in a wide range of environments, while generalist species are limited to specific habitats.

• Specialist species have a narrow diet and habitat preference, while generalist species can adapt to a variety of foods and environments.

• Generalist species are always endangered, while specialist species are always common.

• Specialist species migrate frequently, while generalist species do not migrate.

Multiple Choice

Which of the following best describes a specialist species?

• Has a broad range of food requirements and high adaptability

• Has a narrow ecological niche and specific food requirements

• Is less likely to become extinct due to high adaptability

• Uses a variety of resources and adapts to many environments

Open Ended

Compare the adaptability of specialist and generalist species when environmental conditions change.

Open Ended

Identify ONE characteristic of specialist species and explain how that characteristic makes them more likely to become extinct than generalist species.

Multiple Select

Based on the hare and lynx population graph, which of the following statements are correct?

• Hare population increases when lynx population is low.

• Lynx population increases due to an increase in hare population.

• Increasing lynx population leads to hare population die-off.

• Hare population remains constant regardless of lynx population.

Open Ended

Explain the impact that the canine virus had on the moose population based on the graph.

Fill in the Blanks

A population with a high density is more likely to experience a

outbreak.

Multiple Choice
