Effect of Temperature on Goldfish Respiration

An experiment was conducted to analyze the impact of water temperature on the respiration rate of goldfish. Three tank temperatures were tested: 15°C, 20°C, and 25°C. The respiration rates were measured in breaths per minute after 30 minutes in each temperature condition. The results showed that the respiration rate was highest at 25°C, followed by 20°C and then 15°C.

Based on the experiment, what conclusion can be made regarding the effect of temperature on the respiration rate of goldfish?
