Farmers within the hyacinth macaw’s range set yearly grass fires that often destroy the bird’s nesting trees. Which of the following best explains why this action would lead to either a short-term or long-term effect on the hyacinth macaw population?
A) Short-term effect, because the hyacinth macaws can nest in cliffs
B) Short-term effect, because the nesting trees will grow back quickly
C) Longterm effect, because the hyacinth macaws’ nesting sites are destroyed

In 1995, gray wolves were restored to Yellowstone
National Park. As a result, the gray wolves began to control the park’s large elk population, which had been overeating trees growing along the park’s streams. The recovery of the trees, in turn, has cooled the stream flows to normal temperatures.
Which of the following organisms would probably benefit most from the streams’ cooler waters?
A) Migrating birds that need nesting areas
B) Native trout that live in the park’s water
C) Trees that provide habitats for native birds
D) Beavers that use willow branches to make dams

Which of the following conclusions is best supported by the information given above?

B) The amount of sea ice available for polar bears has generally increased since 1978.
C) The extent of Arctic sea ice each year depends on the size of the polar bear population.
D) The polar bears’ survival is threatened because less sea ice makes it more difficult for them to hunt.
