Free Response:
Read the following article from the Fremont Inquirer and answer the questions that
follow (See next page).
(a) As mentioned in the article, there are several possible explanations for the increase in
mountain pine beetles.
(i) Provide one reason why fire-suppression policies lead to increased beetle activity.
(ii) Reduced winter mortality of beetle larvae is likely a consequence of global climate
change. Describe TWO ways that the activities of the beetles might enhance climate
change.
(b) The widespread death of trees leads to a series of changes in a forest ecosystem. Identify
TWO physical changes that occur in the forest ecosystem as the result of the death of
mature trees. For each physical change you identify, describe an impact of that change on
the forest ecosystem.
(c) As the article states, the number of managed honeybee colonies has dropped significantly
over the past few decades. Describe TWO specific economic consequences of the
collapse of the managed honeybee colonies.
(d) Pollination by native insects is considered an ecosystem service. Identify a different
ecosystem service and explain how that service benefits human society.
