In ectotherms and endotherms heat can be lost through:
Correct answer: D. All (A), (B) and (C)
- A. Evaporation
- B. Radiation
- C. Convection
- D. All (A), (B) and (C)
Explanation
In both ectotherms and endotherms, heat can be lost through evaporation, radiation, and convection.Both ectotherms and endotherms can lose heat through evaporation. This occurs when water on the surface of the organism evaporates, taking heat with it. For example, sweating in mammals and reptiles licking their skin to cool down are both mechanisms of heat loss through evaporation.Heat can be lost through radiation in both ectotherms and endotherms. Radiation is the transfer of heat energy in the form of electromagnetic waves. Both cold-blooded and warm-blooded animals can emit heat through radiation to their surroundings.Convection involves the transfer of heat through the movement of fluids, such as air or water. Both ectotherms and endotherms can lose heat through convection. For instance, a warm-blooded animal can lose heat to the surrounding air, and a cold-blooded animal can lose heat to water it is immersed in.

About Homeostasis
Homeostasis maintains a stable internal environment through the kidney and urinary system, thermoregulation and excretion. The kidney topics include filtration, selective reabsorption, urine formation and water balance, while thermoregulation involves sweating, vasodilation, vasoconstriction and hormonal control; excretion is different from egestion, which removes undigested food.
