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

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.

What is the danger in eating large fish like tuna and shark?

• They may be invasive species.

• If abundant, they may lead to a crash in other species.

• If they are high on the food chain they may contain high levels of mercury or POP's like PCB's

• They may contain too many nutrients from fertilizers.

What is it called when a persistent pollutant (like mercury or PCBs) builds up in the tissues of an organism as they continue to eat something that contains the pollutant

• Subsidence
• Biomagnification
• Tragedy of the commons
• Bioaccumulation
