Question 14
Read the passage about plankton algae.
Plankton algae are microscopic algae that live in water. In a healthy pond ecosystem, plankton algae can be beneficial. They are fed on by zooplankton which, in turn, become food for fish. Plankton algae can grow rapidly when they are supplied with nutrients such as nitrogen and phosphorous. When fertilizer runs off from a farmer's field into a nearby pond, the extra nutrients can cause the plankton algae to grow too quickly and form a bloom. The bloom of algae can cover the entire surface of the pond.
Which argument correctly predicts an effect of an algal bloom on the pond ecosystem?
a
The temperature of the water will increase.
b
The number of decomposers will decrease.
c
The underwater plant populations will decrease.
d
The populations of native fish will increase.
Question 15

Which factor might have contributed to this decline?
a
habitat destruction
b
an energy-rich diet
c
fewer natural predators.
d
overproduction of bird offspring

Question 19
NEWS BULLETIN
Directions: The information is from a news bulletin about wildfires. Use the news bulletin to answer any questions that follow.
The wildfires suffered by East Texas in the fall of 2011 were extremely severe. Wildlife biologists have determined that the fires burned meadow and forest ecosystems to the extent that grasses and wildflowers will not recover quickly. The decreased herbaceous ground cover has diminished food for native insects. As insects have declined, the Houston toad has lost both ground cover for homes and a major source of food. It may take years for Texas' population of Houston toads to reach its former level.
The Parks and Wildlife Department of the State of Texas is interested in increasing the population of Houston toads. Scientific research by wildlife biologists will help the state of Texas achieve this goal. Their work will likely show that the growth of herbaceous ground cover should be
a
redirected until the plants can support a stable breeding population of Houston toads.
b
prevented until the plants can support a stable breeding population of Houston toads.
c
slowed down until the plants can support a stable breeding population of Houston toads.
d
monitored until the plants can support a stable breeding population of Houston toads.

Question 21
Can one individual person have an impact on their environment?
a

Yes, because everything impacts an environment, no matter how small.
c
No, because only groups of people make an impact on an environment.
d
No, because only plants and animals make an impact on an environment.
