What most likely causes the trends in oxygen concentration shown in the graph above?
A) The water becomes colder at night and thus holds more oxygen.
B) Respiration in most organisms increases at night.
C) More organisms are respiring at night than during the day.
D) Photosynthesis produces more oxygen than is consumed by respiration during the day.
Answer: D) Photosynthesis produces more oxygen than is consumed by respiration during the day.
