- Q1A company has several factories around the world and has decided to transition from burning fossil fuels to using alternative energy resources. How could a decrease in burning fossil fuels impact the atmosphere?It could decrease the carbon dioxide levels of the atmosphere.It could decrease the carbon dioxide levels of the atmosphere.It could increase the nitrogen levels of the atmosphere.it could decrease the oxygen levels in the atmosphere30s
- Q2Some factories can increase the amount of thermal pollution by dumping heated water into lakes and rivers. How can this type of pollution affect aquatic environments?It can increase the amount of dissolved oxygen in the environment.It can reduce the decomposition rate of organisms in the environment.It can reduce the number of aquatic species in the environment.It can increase the life expectancy of animals in the aquatic environment.30s
- Q3Since 1901, global surface temperatures have risen at an average rate of 0.13°F every ten years. In which way could the average increase in global temperatures influence Earth?by decreasing erosion within coastal ecosystemsby increasing the amount of flooding because of rising sea levelsby increasing the formation of sea ice within polar regionsby decreasing periods of drought in all water systems30s
- Q4Which example describes an abiotic factor that could impact the diversity of an ecosystem?The introduction of an invasive species can change the amount of available resources in an ecosystem.An increase in prey can impact the number of predators in an ecosystem.An increase in the amount of acid rain can change the pH of the soil in an ecosystem.The competition for food can impact the survival rate between members of the same species in an ecosystem.30s
- Q5Kudzu, a vine covering many acres of North Carolina, was introduced to the United States in 1876 to control erosion. Over the years, scientists found that kudzu creates problems by growing rapidly and preventing other plants from getting sunlight. Which best describes kudzu?a noncompetative speciesan invasive, nonnative speciesan abiotic factoran agent of erosion30s
- Q6Which could MOST LIKELY have a lasting negative impact of the biodiversity of an area?selective cuttingan increase in plant populationsclear-cuttinga reduction in the use of fertilizers30s
- Q7Which BEST describes the relationship between carrying capacity and Earths resources?A population that is below the carrying capacity will have an increase in contagious diseases.A population that is above the carrying capacity will experience an increase in plant production.A population that is above the carrying capacity will have a decrease in natural resources.A population that is below the carrying capacity will experience a decrease in freshwater resources.30s
- Q8How could the exponential growth of the human population impact regions throughout the world?It could lead to a decrease in the amount of pollution in the regions.It could lead to an increase in the biodiversity of the regions.It could lead to an increase in the demand for food in the regions.It could lead to a decrease in the demand for land within the regions.30s
