What is mode of nutrition in porifera?

Answer 1

Porifera, commonly known as sponges, exhibit a mode of nutrition that is primarily filter-feeding. They draw water through their porous bodies, trapping small particles such as bacteria and plankton, which are then absorbed by specialized cells called choanocytes. This process allows sponges to obtain nutrients while also facilitating gas exchange and waste removal. As a result, sponges play a vital role in their aquatic ecosystems by filtering and cleaning the water.
