Once the experiment was completed, the results of the experiment were reviewed. The null hypothesis was rejected and the alternative hypothesis, change in temperatures does effect goldfish respiration rate, was accepted. Goldfish are considered ectotherms which mean that their body temperature changes as their environment temperature changes (White and Campo 2015). Ectotherms have two aquatic ectotherm strategies they use to cope with cold temperatures. The goldfish in this experiment used the first strategy, which is to slow down their metabolism. By slowing down their metabolism the need for oxygen and food is decreased, which allows for them to breathe at slower rates. In the graph it is shown by fish one and three that as the temperature
