Many small organisms meet their O₂ requirements by gas diffusion across their membranes. What is a simple, effective method for replenishing O₂ levels in a small organism's immediate environment? A) Increase the O₂ levels in the boundary layer. B) Decrease metabolic rates to decrease O₂ use. C) Decrease the PO₂ pressure gradient across the boundary layer. D) Decrease the partial pressure gradient for diffusion. E) Mix and/or replace water in the boundary layer surrounding the organism.
