Why are rapids and other types of whitewater more highly oxygenated than bogs and other stagnant-water habitats?

More surface area is exposed to the atmosphere in rapids and other types of whitewater than in stagnant-water habitats.

More decomposers release oxygen in rapids and other types of whitewater.

Rapids have a lower oxygen partial pressure.

Bogs and other stagnant-water habitats have a larger surface area over which oxygen can diffuse back into the atmosphere.
