16.
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) Long-term effect, because the hyacinth macaws’ nesting sites are
destroyed
D) Long-term effect, because yearly fires do not preven more dangerous
fires

17. 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 over-eating 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

18.
Which of the following conclusions is best supported by the information
given above?
A) Polar bears will adapt to a los of Arctic sea ice and find new sources of
food.
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.

19. The theory of natural selection explains howA) farmers develop certain types of crop plants.
B) variations appear in a species.
C) environments change over time.
D) useful traits spread through a population.

20. What is most likely to happen if an environment
changes and a species does not have variations that
are helpful in the new conditions?

environment.

adaptations.
C) A new species will form from the existing species.
