The Effect of Hot and Cold Temperatures on the Metabolic Rate of Ectothermic Super worms

Mckenzie Bedford, Hannah Sutton, Araya Fetters, Dalton Cunningham, Tyler Ryan


This experiment was designed to determine the relationship between metabolic rate and ambient temperatures of Ectotherms. In order to identify this, we utilized three chambers that were set at different ambient temperatures. We placed the super worms in these chambers for an interval of seven minutes and recorded the change in CO2 levels as well as the temperature of the chamber. After performing this study, we concluded that temperature does correlate with metabolic rate. Supporting our hypothesis, we found that in warmer temperatures the CO2 rate was increased indicating that metabolic rate was also increased.
