Question

Quizplus · Accepted Answer

An organism whose temperature is similar to its surroundings is called an ectotherm. The term ectotherm is often used interchangeably with the term poikilotherm, which means an organism whose body temperature fluctuates with the temperature of its environment. Endotherms, on the other hand, are organisms that can regulate their body temperature internally, and are commonly referred to as warm-blooded organisms. Therefore, choices A and D are incorrect. Osmoregulators are organisms that maintain a constant internal water balance, and are not related to temperature regulation, so choice E is also incorrect.
