Which feature most directly helps explain why some organisms in rivers and streams cling to surfaces or swim against the current?

  1. A

    They favor organisms that require still water and cannot tolerate flow.

  2. B

    They favor organisms able to cling to surfaces, swim against currents, or live in slower-flowing margins.

  3. C

    They lack the transport of nutrients and sediments.

  4. D

    They are classified by the seasonal mixing of warm surface water with deeper lake water.

  2. B

    Nutrients carried only by tides from the shore

  3. C

    Light captured by trees growing on the ocean floor

    Tropical wet forest

  2. B

    Savanna

A hiker climbs a mountain and observes vegetation changing from forest to low-growing plants. Which explanation best accounts for this pattern?

  1. A

    Mountain slopes become warmer with elevation, favoring tropical vegetation.

  2. B

    Higher elevations receive more direct sunlight than the equator, preventing vegetation zones.

  3. C

    Higher elevations are generally cooler, so vegetation zones can resemble those at higher latitudes.

  4. D

    Elevation affects aquatic biomes but does not influence terrestrial vegetation.

Moist air rises over a mountain range. Which precipitation pattern is most likely on the two sides of the range?

  1. A

    The windward slope is wetter, while the leeward side can be drier in a rain shadow.

  2. B

    The leeward side is wetter because descending air releases more moisture.

  3. C

    Both slopes receive equal precipitation because elevation affects only temperature.

  4. D

    The windward slope is drier because rising air loses all its moisture before reaching it.

In a lake, algae and aquatic plants can photosynthesize only in the upper layer that receives sufficient sunlight. What is this layer called?

  1. A

    The deep-water zone, because pressure increases with depth

  2. B

    The photic zone, because it receives enough light for photosynthesis

  3. C

    The bottom zone, because nutrients are always more abundant there

  4. D

    The brackish zone, because freshwater and seawater mix

A stream has fast-flowing sections and slower margins. Which adaptation would best help an organism persist in the fast current?

  1. A

    Organisms must all remain suspended in the fastest current.

  2. B

    Organisms survive by avoiding contact with river surfaces.

  3. C

    Current speed has little effect on where organisms can live.

  4. D

    Some organisms cling to surfaces, swim against the current, or use slower-flowing margins.
