knowing that as the steepness of a concentration graident increases, the rate of diffusion increases, explain how a single celled organisms would respond in an oxygen rich pond compared to an oxygen poor pond.
I'm not really sure but in an oxygen poor pond there is a small difference between the concentration of the oxygen in the water compared to the oxygen concentration in the single celled organisms. Therefore, diffusion occurs slowly. does that mean the organism breaths at a slower rate and in the pond that is oxygen rich, it will breath faster. It doesn't sound right to me. Can anyone explain this to me?

I means as oxygen content increases, then the respiration rate increases, and metabolism increases.
