Why Asconoid body design of sponges is not as efficient as Syconoid and Leuconoid?

Asconoid sponges have a simple, tubular body structure that limits the surface area available for filter feeding, making them less efficient than Syconoid and Leuconoid sponges. In contrast, Syconoid sponges have folded body walls that increase surface area, while Leuconoid sponges possess a complex network of chambers that further enhance feeding efficiency and water flow. This increased complexity allows for greater nutrient absorption and better adaptation to varying environmental conditions. Consequently, Asconoid sponges are generally less capable of thriving in competitive or nutrient-rich environments compared to their more advanced counterparts.
