Nutrient Loading In Lake Erie

Lake Erie, part of the Great Lakes, is vital for regional industries and public health. Despite past improvements, water quality has declined due to algal blooms caused by nutrient runoff from farming. Research funded by the NSF aims to address these issues through better farming practices and technology. Collaborative efforts are underway to restore the lake, which can recover quickly once pollution is reduced.

Which of the following is NOT a use of Lake Erie's water?

• Sport fishing

• Drinking water

• Irrigating crops

• Generating electricity

What was a significant environmental issue Lake Erie faced in 2011?

• Toxic blue-green algae bloom

• Drought

• Oil spill

• Invasive species

What is the primary nutrient responsible for algal blooms in Lake Erie?

• Calcium

• Potassium

• Nitrogen

• Phosphorus

How do changing rainfall patterns contribute to nutrient runoff into Lake Erie?

• They reduce the amount of rainfall, concentrating nutrients.

• They cause more intense spring rainfall, leading to runoff.

• They increase evaporation rates.

• They have no effect on nutrient runoff.

What technology helps farmers apply fertilizers more efficiently?

• Variable rate technology

• Hydroponics

• Drip irrigation

• Pesticide spraying

What is the concept of 'the four Rs' in nutrient management?

• Right place, right amount, right time, right method

• Right crop, right soil, right climate, right season

• Research, report, regulate, restore

• Reduce, reuse, recycle, recover

What is a hopeful aspect of Lake Erie's recovery from pollution?

• It rebounds quickly once pollution stops.

• It has a diverse ecosystem.

• It has a large volume of water.

• It is isolated from other water bodies.
