Exam 34: the Biosphere: an Introduction to Earths Diverse Environments

If you travel through Ecuador from west to east, you will pass through tundra, taiga, temperate forest, and tropical forest. Which of the following climatic factors remains constant on such a trip?

-In what ways are zones A and C similar to other biomes?

Pronghorn antelopes are well adapted for dry conditions with extremes of temperature, especially cold. As global climate change causes the area where the pronghorn live to change, not only in temperature but also in what plants grow there and what predators and prey live there, what is likely to happen to the pronghorn?

-Forest destruction would have the greatest impact on which arrow?

Which of these is an example of natural selection acting on genetic variation resulting in evolutionary adaptation?

Which of the following biomes is dominated by coniferous trees adapted to surviving long, harsh winters and short, wet summers?

Which of the following statements about temperate broadleaf forests is true?

The primary source of energy for hydrothermal vent communities is

Species in widely separated but similar biomes often appear to display similar characteristics because of

After reading the paragraph below, answer the questions that follow. California condors, large, predatory birds that were previously on the edge of extinction, have benefited from a program that raises birds in captivity and then releases them into the wild. The reintroduction program, however, is having variable success. -Which of the following provides the best evidence to help develop a hypothesis about what is causing the difficulties faced by a coastal condor population?

-Which arrow in this image of the global water cycle includes transpiration?

In which of the following biomes would you expect to find the highest abundance of large, grazing mammals?

Which of the following is characteristic of the chaparral biome?

When people speak of the "rain shadow" of the Himalayan mountains, where the Gobi desert is, they are referring to the

Why is the runoff from fertilized agricultural fields, even if free of pesticides, often harmful to the ecosystems of temperate lakes?

The greatest annual input and least seasonal variation in solar radiation occurs in the

After reading the paragraph below, answer the questions that follow. The largest estuary in the United States is the Chesapeake Bay, which extends through six states, including Maryland, Virginia, and Pennsylvania. The bay is one of the most productive natural areas in the world. It is home to thousands of plants and animals, including many commercially important species. The water of the bay is relatively shallow. Many areas are no more than 10 feet deep, with an average depth of 30 feet. Light penetrates the shallow water and supports the submerged plants that provide food and shelter for the many species living in the bay ecosystem. However, like many estuaries, the bay receives large amounts of fertilizer runoff from farms, lawns, and wastewater treatment facilities. -Which of the following is the most probable sequence of events when fertilizer runoff reaches the bay?

Most of the best agricultural soils in the United States are found in areas that were formerly
