Quizplus · Accepted Answer

The surface area available for absorption is the most important factor in determining how rapidly an organism can absorb nutrients. The more surface area that is available, the more nutrients can be absorbed at once. This is why many organisms have specialized structures to increase their surface area for absorption, like the villi in the small intestine of humans. The other choices, diffusion, passive mechanisms, and volume, may have some effect on nutrient absorption, but they are not as critical as surface area.
