Organisms use different strategies to regulate body temperature and metabolism. i. Endotherms use thermal energy generated by metabolism to maintain homeostatic body temperatures. ii. Ectotherms lack efficient internal mechanisms for maintaining body temperature, though they may regulate their temperature behaviorally by moving into the sun or shade or by aggregating with other individuals. c. There is a relationship between metabolic rate per unit body mass and the size of multicellular organisms—generally, the smaller the organism, the higher the metabolic rate.

An experiment to measure the rate of respiration in crickets and mice at 10° C and 25° C was performed using a respirometer, an apparatus that measures changes in gas volume. Respiration was measured in m. L of O 2 consumed per gram of organism over several five-minute trials, and the following data were obtained. According to the data, the crickets at 25° C have greater oxygen consumption per gram of tissue than do the crickets at 10° C. According to the data, the mice at 10° C demonstrated greater oxygen consumption per gram of tissue than did the mice at 25° C. This trend in oxygen consumption is different in mice and crickets. EXPLAIN THE RESULTS OF THIS MOUSE/CRICKET TEMPERATURE EXPERIMENT
