Why may fish get less dissolved oxygen in warm pond water?
Answer and explanation
Correct answer: Because gases are less soluble in warm water
Oxygen is a gas, and its equilibrium solubility in water generally decreases as temperature rises. Consequently, warm pond water can hold less dissolved oxygen for fish and other aquatic organisms. This does not mean oxygen becomes solid or that the absence of salt is the direct reason. Biological activity and pollution can also affect oxygen levels, but the question asks for the temperature effect.
