Question

select two of the following changes that are likely to occur over time as a result of warming temperatures in yellowstone national park.

the number of whitebark pine beetles will likely decrease.

the number of whitebark pine beetles will likely increase.

the number of squirrels and grizzly bears will likely decrease.

the number of squirrels and grizzly bears will likely increase.

Explanation:

Warmer temperatures can lead to an increase in whitebark pine beetles as they may have more favorable conditions (e.g., less cold - related mortality). If the beetles kill more whitebark pine trees, the seeds (which are food for squirrels and grizzly bears) will be less available. This would likely lead to a decrease in the number of squirrels and grizzly bears.

Answer:

B. The number of whitebark pine beetles will likely increase.
C. The number of squirrels and grizzly bears will likely decrease.
