Accepted Answer

Availability of sunlight

Question 5

A region experiences low and unpredictable rainfall, and its vegetation is adapted to conserve water. Which biome does this describe?

Accepted Answer

Desert

Question 6

Which equation best represents the net movement of water vapor in the global water cycle?

Accepted Answer

$$	ext{Evaporation}_{	ext{sea}} \u003e 	ext{Precipitation}_{	ext{sea}}$$

Question 7

Accepted Answer

Tropical forest

Question 8

Which of the following best explains why the seasons occur on Earth?

Accepted Answer

The Earth’s permanent tilt of $$23.5^{\circ}$$ causes different hemispheres to receive varying amounts of solar energy throughout the year.

Question 13

Which biome is most likely to experience periodic fires, hot dry summers, and cool rainy winters?

Accepted Answer

Chaparral

Question 14

Which of the following best describes the photic zone in aquatic biomes?

Accepted Answer

The region where photosynthesis occurs due to light penetration

Question 15

A city expands into a nearby grassland, replacing native vegetation with buildings and roads. Which ecological insight is most relevant to understanding the impact?

Accepted Answer

Human activities alter both biotic and abiotic components of ecosystems.

Question 16

Which biome is most likely to be inhabited by large grazing mammals and insects, with dramatic seasonal variation and scattered trees?
