Which outcome sharply declines amphibian egg oxygen uptake during pond eutrophication?

💡 Explanation

During eutrophication, increased algal respiration depletes oxygen near eggs; decreasing the oxygen gradient, which relies on high oxygen differential in water near egg via convection, reducing diffusion. Therefore, a diminished gradient lowers uptake, rather than increased egg limitations, hemoglobin defects, or faster consumption, unrelated to eutrophication impact.
