Fish Behavior and Water Temperature Hypotheses

Hard Conflicting Viewpoints Comparing Hypotheses

In a recent study on the effects of water temperature on fish behavior, two researchers, Dr. Reynolds and Dr. Clarke, put forward contrasting hypotheses.

Dr. Reynolds proposed that higher water temperatures would lead to increased activity levels in fish, suggesting that warmth stimulates metabolic rates and encourages foraging behavior. Conversely, Dr. Clarke hypothesized that elevated temperatures would cause increased stress in fish, leading to decreased activity as they seek cooler water to escape discomfort.

Which of the following conclusions is most closely aligned with Dr. Clarke's hypothesis?
