Poikilothermic organisms have body temperatures that ____.

D) allow them to survive in very warm climates only

Question

Quizplus · Accepted Answer

Poikilothermic organisms (or ectotherms) cannot regulate their body temperature internally, so their body temperature is the same as the temperature of their environment. Their physiological processes (like metabolism and activity levels) are influenced by changes in temperature, which is why they can be more active in warmer conditions and less active in cooler conditions.
