Question

Quizplus · Accepted Answer

The evolution of an alimentary system, or digestive system, is primarily to allow for extracellular digestion. This means that food is broken down outside of the cells, allowing for more efficient and complete digestion. Storage of food before digestion (A) and intracellular digestion (B) are not the primary functions of the alimentary system. Filter feeding (D) and fluid feeding (E) are feeding strategies used by some organisms, but are not directly related to the evolution of the alimentary system.
