A fish swimming into a bog environment in Ontario would likely have which of the following as its greatest physiological challenge?
A) The high water flow would make the fish expend more energy.
B) The high temperature would stress the fish by denaturing its proteins.
C) The low nitrogen content would make it difficult for the fish to synthesize proteins.
D) The low oxygen content would make it difficult for the fish to swim aerobically.

Question

Quizplus · Accepted Answer

The low oxygen content would be the greatest physiological challenge for a fish swimming into a bog environment. Fish require oxygen for cellular respiration and low oxygen levels can lead to reduced aerobic activity and potentially death. The other options may also present challenges, but not to the same extent as low oxygen levels.
