Hypothesis
Prior to conducting the lab, it was hypothesized that Zophobas morio will have a higher rate of oxygen consumption than Tenebrio molitor. The hypothesis was made on the basis of supporting evidence stating that oxygen consumption in an organism at rest increases with body mass (Bartholomew, 1977). Since the size of Zophobas morio is significantly bigger than the size of Tenebrio molitor, it was hypothesized that they will consume more oxygen in mL/hour.
Results
The graph in Figure 1 shows the rate of oxygen consumption of species Zophobas morio weighing 1.93g at a temperature of 20.5°C. The average rate of oxygen consumption for each tube is indicated by the line of linear regression. The data collected with a sample size of six experimental tubes over three trials had an average oxygen consumption rate or mean of 0.32033 mL/O2/hour. The experimental tube 2 of trial 3 showed a respiration rate higher than the general trend of other experimental tubes (atypical), which was caused due to vigorous organism movement. The data had a significant error of ± 0.10 and the standard …show more content…
The average rate of oxygen consumption for each tube is indicated by the line of regression. The data collected with a sample of six experimental tubes over three trails had an average oxygen consumption rate or mean of 0.23701 mL/O2/hour. Unlike treatment 1 which contained Zophobas morio, this data showed no atypical data. The rate of respiration for the species Tenebrio molitor did not vary very much from tube to tube. The data had a significant error of ± 0.04 and standard deviation of 0.087 mL
