The factor in the environment that might decrease the Daphnia's heart rate is:
**b Cold water; slows metabolic processes.**
Cold water can lead to a decrease in metabolic activity overall, which includes a reduced heart rate in organisms like Daphnia. Oxygen-rich water, caffeine, and darkness (while it might lower activity levels) do not typically result in a decrease in heart rate in the same direct way as cold water does.
