Exam 52: An Introduction to Ecology and the Biosphere

Coral reefs occur on the southeast coast of the United States but not at similar latitudes on the southwest coast. Differences in which of the following most likely account for this?

Use the following figure to answer the question below. In the figure, which number would designate the biome with the highest variation in both annual precipitation and temperature?

Suppose that the number of bird species is determined mainly by the number of vertical strata found in the environment. If so, in which of the following biomes would you find the greatest number of bird species?

Which statement about dispersal is false?

In areas of permafrost, stands of black spruce are frequently observed in the landscape, while other tree species are noticeably absent. Often these stands are referred to as "drunken forests" because many of the black spruce often "lean over" (that is, they are displaced from their normal vertical alignment). What is the most likely explanation for the unusual growth of these forests in this marginal habitat?

Which of the following causes seasons on Earth?

If you conclude that vegetation at every point on Earth exactly resembles the predicted biome distribution in a climograph, then ________.

If the direction of Earth's rotation reversed, the most predictable effect would be ________.

Generalized global air circulation and precipitation patterns are caused by ________.

Which of the following might be an investigation of microclimate?

Organisms evolve over generations to become adapted to the environmental conditions to which they are exposed. The diversity of organisms that occurs in any particular area thus may be largely determined by the abiotic factors limiting survivorship and reproduction of organisms in a region. Which of the following limit the range of Saguaro cactus in North America? I.pollinators II.sunlight III.precipitation IV.temperature

The eight climographs show yearly temperature (line graph and left vertical axis) and precipitation (bar graph and right vertical axis) averages for each month for some locations on Earth. Which climograph shows the climate for location 5?

In deep water, which of the following abiotic factors would most limit primary productivity?

Which of the following examples demonstrate an ecological effect leading to an evolutionary effect?

In mountainous areas of western North America, north-facing slopes would be expected to ________.

Which of the following is responsible for the differences in summer and winter temperature stratification of deep temperate zone lakes?

Use the diagram showing the spread of the cattle egret, Bubulcus ibis, since its arrival in the New World, to answer the question. The range of cattle egrets has expanded between 1937 and today. How would an ecologist likely best explain the expansion of the cattle egret?

Generally speaking, deserts are located in places where air masses are usually ________.

The eight climographs show yearly temperature (line graph and left vertical axis) and precipitation (bar graph and right vertical axis) averages for each month for some locations on Earth. Which climograph shows the climate for location 1?

Which of the following areas of study focuses on the exchange of energy, organisms, and materials between ecosystems?
