Water pollution as a result of fertilizer runoff from farms is harmful because it initially

• A) changes the chemical composition of nearby streams and lakes
• B)adds ozone to the atmosphere, increasing global temperatures
• C)decreases the water temperature of streams and lakes
• D)decreases the amount of nutrient recycling in lakes

A growing mass of plastic garbage is collecting in an area of the Pacific Ocean. This is caused by plastic garbage that is discarded by people, and it ends up in rivers that carry it to the ocean. Over time, ocean currents cause it to accumulate in this area of the Pacific. Currently, the mass is estimated to cover an area of ocean twice the size of Texas. As these plastics slowly break down, chemicals enter the water, and can enter ocean organisms that we might eventually use for food. This sequence of events illustrates that

• A)humans modify ecosystems as a result of population growth, consumption, and technology
• B)human activities that degrade ecosystems result in an increase in diversity of ecosystems
• C) when humans alter ecosystems by adding specific organisms, serious consequences could result
• D)industrialization brings a reduced demand for fossil and nuclear fuels

A change in the acidity of mountain lakes would most likely be a result of

• A) ecological succession of the area at the top of the mountain
• B) the introduction of new species into the lakes
• C) air pollution from smoke stacks miles away
• D) planting grasses and shrubs around the lakes

Water from nearby rivers or lakes is usually used to cool down the reactors in nuclear power plants. The release of this heated water back into the river or lake would most likely result in

• A) an increase in the sewage content in the water
• B) a change in the biodiversity in the water
• C) a change in the number of mutations in plants growing near the water
• D) a decrease in the amount of sunlight necessary for photosynthesis in the water

• B) the stimulation of a rapid rate of evolution
• C) the elimination of many species of aquatic life
• D) an increase in agricultural productivity

Many homeowners and businesses are installing solar electric systems. Greater use of solar electric systems benefits the environment because it

• A) depends on the greater use of fossil fuels
• B) conserves nonrenewable resources
• C) produces gases that cause global warming

Some time ago, there were thousands of California condors in North America. Large numbers were poisoned from lead in bullets that were used to kill the animals the condors fed on. An effort was made to help save this large scavenger. There are now more than 350 California condors in North America. The condors most likely increased in number because humans decided to

• A) produce lead-resistant condors through asexual reproduction
• B) pass laws against using lead bullets to kill animals used by condors for food
• C) introduce plants that didn't absorb the lead from discharged bullets
• D) produce lead-resistant prey for the condors through genetic engineering
