In a recent investigation into the effects of pharmaceuticals on aquatic life, two researchers, Dr. Green and Dr. Silver, presented conflicting hypotheses regarding the impact of an antibiotic on fish behavior.
Dr. Green hypothesizes that exposure to the antibiotic will enhance fish agility and foraging efficiency, believing that small doses stimulate metabolic processes beneficial for growth and activity. In contrast, Dr. Silver proposes that the same antibiotic will impair fish behavior, predicting that increased exposure will lead to lethargy and decreased foraging success due to potential toxicity.
Both researchers conducted experiments with similar setups, utilizing the same species of fish, but varied the concentrations of the antibiotic and the duration of exposure. Their results were as follows: Dr. Green reported increased swimming speeds and higher food intake at lower concentrations, while Dr. Silver noted a significant decrease in activity and feeding rates at higher concentrations and a slight decline even at lower doses.
Based on this information, which hypothesis do you think is better supported by the experimental findings?
