Exam 7: Climate and Biodiversity

Heated air masses above the equator move north and south to cooler areas because:

At least half of the known species of terrestrial plants and animals are found in:

Terrestrial ecosystems are referred to as biomes, but water-based ecosystems are not.

The rain shadow effect refers to

A small rodent called the desert kangaroo rat lives in the deserts of the southwestern United States. This animal is somewhat unique among mammals in that it does not drink water, but gets all of its liquid needs met from the water in the seeds it eats. What benefit would this physiological feature have to an animal that lives in a hot, dry climate where water is sparse?

The general effects of elevation and latitude are the same on climate and biomes.

Match the time of year in a temperate deciduous forest with the correct event or situation described below. -wolves and bears are present

A connected loop of deep and shallow ocean currents transports warm and cool water to various parts of the earth.

-Referring to the above graph from a temperate desert observe that the months of March and April are not the warmest, coldest or wettest months in this biome. However, the bloom of desert wildflowers will typically occur in these two months. Explain why this is.

Surface-level ocean currents are caused by

Match the items listed below with the appropriate choice -On the ocean life zones figure, choose the zone that is dimly lit and contains zooplankton.

Climate and vegetation vary with

Match the biome or aquatic system listed below with the description that best characterizes it. -daytime temperatures are very high in summer, but low in winter

Economic services and ecological services are always the same.

Match the time of year in a temperate deciduous forest with the correct event or situation described below. -precipitation is abundant

Most photosynthesis in the open sea occurs in the

Match the items listed below with the appropriate choice -On the ocean life zones figure, choose the zone in which most organisms get their food from marine snow.

Which terrestrial ecosystem has been disturbed by human activity more than any other?

When the algae in coral reefs die off due to environmental stresses, the coral subsequently dies because of lack of food. This process is referred to as

Match the items listed below with the appropriate choice -On the ocean life zones figure, choose the zone that receives enough sunlight for photosynthesis.
