Compared to ectotherms, endothermic animals are likely to be at the greatest disadvantage in ________.
A) very cold environments
B) very hot environments
C) environments with a constant food source
D) environments with variable and limited food sources

Question

Quizplus · Accepted Answer

Endothermic animals, which regulate their body temperature through internal metabolic processes, require a significant amount of energy and thus food. In environments where food sources are variable and limited, they are at a disadvantage compared to ectotherms, which can survive on less energy because they rely on external sources for body heat.
