Question

Quizplus · Accepted Answer

Sea stars are ectothermic organisms that rely on the temperature of their surrounding water to regulate their body temperature. They would have difficulty adjusting their body temperature if the temperature of the water changes rapidly or drastically, such as during a sudden change in ocean currents or a marine heatwave. Unlike sea stars, terrestrial lizards can adjust their body temperature by moving to different locations, such as basking in the sun or seeking Shade. Sharks are also ectothermic but are able to regulate their body temperature to some extent by moving to different depths of water. Hummingbirds are endothermic, meaning they can regulate their own body temperature internally. House flies are also ectothermic but are able to adjust their body temperature by moving to different locations and by using evaporative cooling.
