Q26 - Thermoregulatory Strategies of Endotherms and Ectotherms
Animals possess mechanisms for maintaining their body temperature within permissible levels. For example, they show various responses to changes in room temperature. In addition, animals’ body shapes are optimized to adapt to various climate changes, and their behaviors also regulate their body temperature.
Using the information and data, determine which of the statements are true or which are false.
A. In each ordinary habitat, the body temperature of endotherms is always higher than that of ectotherms.
B. In humans, the body temperature is elevated when the temperature of the hypothalamus is artificially increased.
C. When a female Burmese python incubates eggs, her oxygen consumption in a cold room is less than that in warm room.
D. Ectotherms require less energy than endotherms for homeostasis.
