Multiple Choice

How can variations impact populations when the environment changes?

• Variations can enhance survival and adaptation, allowing populations to thrive in changing environments.
• Variations lead to extinction in changing environments.
• Variations have no effect on population dynamics.
• Variations make populations less adaptable to new conditions.

Multiple Select

Select all the effects (2) that could lead to a decrease in population size due to environmental changes.

• Mating calls may not be heard due to noise pollution.

• Predators see white animals better in less snowy winters.

• Fluffier tails help animals cool in hotter summers.

• Animals with white winter fur coats blend in better in snowy winters.

Multiple Choice

Which of the following is an example of an environmental change that could decrease a population due to a variation?

• Cities cause increased noise pollution, affecting animals with softer mating calls.

• Summers become cooler over time, helping animals with fluffier tails.

• Winter becomes colder and snowier, helping animals with white winter fur coats.

• Cities become quieter, helping animals with softer mating calls.

Multiple Choice
