APES Unit 8 Quiz - Aquatic and Terrestrial Pollution

Endocrine disruptors cause the following impacts to organisms

• increased respiratory rate

• damage to the cardiovascular system

• increased size of individual organisms

• birth defects and cancer

DDT is a POP (Persistent Organic Pesticide) that can act as an endocrine disruptor.  Which would it have the greatest effect on?

• Producers
• Primary Consumers
• Secondary Consumers
• Autotrophs

In a river ecosystem, dissolved oxygen concentrations drop quickly downstream from a point-source input of organic matter into the river due to

• increasing populations of mayfly and stonefly larvae
• increasing bacterial activity as organic matter decays
• decreasing bacterial activity as turbidity increases
• decreasing water temperature

Presence of fecal coliform bacteria suggests that

• a factory polluted the river

• a nearby treatment plant added chlorine to the waste water

• the water is safe for drinking

• untreated animal waste contaminated the water

Which of the following describe the relationship between Dissolved Oxygen (DO) and B.O.D.?

• When DO decreases, the B.O.D. decreases

• When DO decreases, the B.O.D. increases

• When B.O.D. decreases, the DO decreases

• When B.O.D. increases, the DO decreases

Which water quality test will best determine the disruption of photosynthesis caused by cloudy water conditions from sedimentation?

• Temperature

• Salinity

• Dissolved oxygen

• pH

• Turbidity

The process of human activities in urban or agricultural areas that load nutrients into surface bodies of water is known as

• artificial fertilization

• cultural eutrophication

• thermal pollution

• lake stratification

• synthetic primary productivity

Which of the following is a point-source pollutant?

• Sediment loading from erosion

• Runoff of pesticides from croplands

• Animal wastes from feedlots

• Fertilizer runoff from urban areas

• A sewage treatment plant effluent pipe

Which of the following is a non-point source of water pollution

• Effluent from a sewage treatment plant
• BP refiner in Indiana discharging ammonia in a river.
• Runoff of pesticides from regional farms into the Illinois River.
• Hot water discharges from a nuclear power plant.

Increased use of inorganic (lab-made) fertilizers on crops contributes to:

• Hypoxia in the Gulf of Mexico
• Increase in storm severity in southeastern U.S.
• Water shortages in California
• Saltwater intrusion on the East Coast.
