Nourishment is obtained from food through the inner surface area of the intestines. Why is it that a small organism, such as a worm, has a simple and relatively straight intestinal tract, while a large organism, such as a human being, has a complex and extensively folded intestinal tract?
i think this has to with greater surface area to volume ration of earthworm and thus a higher metabolic rate but i am not sure.
Please give a coherent answer
