Which outcome impairs fish respiration in stagnant water?

💡 Explanation

Impaired gas exchange in the gills is caused by lack of fluid motion to maintain the concentration gradients; oxygen transfer via diffusion requires higher oxygen concentrations because, rather than continuous renewal, the stagnant surroundings reach equilibrium.
