Unit 1 test redo

This biome contains plants that are adapted to prevent water loss due to the low average rainfall and high temperatures year-round.

Desert

This biome is characterized by long dry seasons and is dominated by grasses, shrubs, and grazing animals.

Savannah

This biome is warm and wet, with little seasonal variation in temperature and frequent precipitation.

Tropical rain forest

The diagram below shows a simplified carbon cycle.

Which of the following major storage reservoirs of carbon, stored in the form of carbon dioxide, is not represented in this diagram?

The ocean

The diagram below shows a simplified carbon cycle.

Based on the diagram above, which of the following processes reduces the amount of carbon dioxide in the atmosphere?

Photosynthesis

The diagram below shows a simplified carbon cycle.

The diagram below shows a simplified carbon cycle.

Decomposition

The diagrams above show an area that was once a pasture that has since undergone changes to the vegetation over time. Which of the following changes in the hydrologic cycle is most likely to occur as a result of the change in vegetation in the area?

Increased infiltration

Which letter correctly identifies the part of the hydrologic cycle that is most directly affected by impervious building materials, such as concrete and asphalt?

D

Which letter correctly identifies a process of the hydrologic cycle in which the phase of water is changed from a liquid to a gas?

B

The diagram shows the amount of phosphorus measured in teragrams ( 1 teragram = 1×1012 grams), in the various reservoirs of the phosphorus cycle.

Which of the following is the best explanation for why there is such a small amount of phosphorus that moves into aquatic systems?

There is not a gaseous phase of the phosphorus cycle, and therefore the movement of phosphorus into oceanic reservoirs is very slow

According to the diagram, the movement of phosphorus between biological organisms and soil is in a steady state in an undisturbed system. Which of the following best explains the reason for this steady movement?

Readily available organic phosphorus in the soil is assimilated by plants.

Based on the diagram, which of the following reservoirs contains the most phosphorus?

Sediments
