Aquatic _______ are in a double bind, because their demand for oxygen increases as the temperature of their environment increases, but the oxygen content of water declines with increasing water temperatures.

Question

Quizplus · Accepted Answer

Ectotherms are organisms whose body temperatures are determined by their environment. As the temperature of their environment increases, their metabolic rate increases and they require more oxygen for respiration. However, the oxygen content of water decreases as the water temperature increases, making it difficult for ectothermic aquatic organisms to obtain sufficient oxygen.
