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
