E)honeybee in a hive.

Question

Quizplus · Accepted Answer

Sea stars are ectothermic and have limited behavioral options to adjust their body temperature since they cannot move from their habitat, which is the intertidal zone. In contrast, terrestrial reptiles like lizards (Choice A) are capable of basking in the sun or seeking shade to regulate their temperature. Bluefin tuna (Choice C) can use regional endothermy by using their muscles to generate heat and keep their body temperature higher than the surrounding water. Hummingbirds (Choice D) are endothermic and can regulate their body temperature internally. Honeybees (Choice E) can also regulate their hive temperature by altering the behavior of worker bees.
