Mexico City has been labeled the city with the worst air pollution ever recorded. The air over Mexico City exceeded ozone limits set by the World Health Organization on more than 300 days in one year. Which would be an effect of air pollution on organisms?

• slower growth of plants due to changes in temperatures caused by ozone

• exposure to more ultraviolet radiation from the Sun due to smog layers

• faster growth of plants due to nutrients in particulate pollution

• more respiratory problems in animals due to ozone

A ship sank in the Atlantic Ocean, near Cape Town in South Africa, and spilled 1300 tons of oil. Which of these would be the MOST likely effect on the ocean ecosystem from this spill?

• Ocean plankton would increase after obtaining nutrients from oil.

• Predators would increase as animals killed by oil were eaten.

• Sea birds would be decrease due to oil on their feathers.

• Bottom-dwelling shellfish would be unaffected.

Burning fossil fuels produces sulfur dioxide (SO2) and nitrogen oxide (NO). These compounds react with water vapor to produce acid rain. What is the MOST likely effect of acid rain on the environment where it falls?

• Fish in lakes and ponds will grow more slowly.

• Algae in lakes and ponds will grow faster

• Predators in forests will switch to different prey.

• Trees and shrubs in forests will grow taller.

Census data show that the human population doubled from 2.65 billion in 1953 to 5.3 billion in 1990. If it continues to double at this rate, the human population could reach 10 billion by the year 2020. Which BEST explains how this rate of human growth can harm the environment on which humans depend?

• by speeding development of sustainable technologies

• by pushing resource use to higher, nonrenewable levels

• by decreasing the cycling of matter through ecosystems

• by increasing the variety of ecosystems worldwide

As a result of human activity, many lakes in Florida have increased levels of nutrients that support algal growth. These algae grow very rapidly, then die and decompose. What impact does this overgrowth of algae MOST likely have on the lake ecosystem?

• The number of fish species increases.

• The volume of lake water increases.

• The buildup of bottom sediments decreases.

• The amount of dissolved oxygen decreases.

Sooj learned that whales use vocalization to navigate and to communicate with other whales. Some scientists think that noise pollution in whale habitats may harm whale populations. What would be the MOST likely effect of noise pollution on whales?

• alteration of whale genetic material

• reversed flow of energy through whale habitats

• reduced populations of food organisms in whale habitats

• separation of whale family groups

How would a reduction in the processing of fossil fuels impact society?

• Petroleum products would become more expensive and pollution would increase.

• Petroleum products would become less expensive and pollution would decrease.

• Petroleum products would be conserved and pollution would increase.

• Petroleum products would be conserved and pollution would decrease.
