As Oxygen Concentration in Sea Water Decreases

Question

As oxygen concentration in sea water decreases
A) Oxygen consumption decreases proportionately
B) Oxygen consumption is about the same over a broad range of ambient concentration
C) Metabolic rate tends to increase
D) Body temperature increases

Accepted Answer

Oxygen consumption in many marine organisms remains relatively constant over a wide range of ambient oxygen concentrations due to physiological adaptations that allow for efficient oxygen uptake and utilization, even as the availability of oxygen decreases.
