Simple advanced and complex sponges
WebbSponges receive the largest quantities of carbon from the algae, phytoplanktons, and corals respectively. That’s by heterotrophic feeding, sponges can quickly deplete carbon in the surrounding water. Therefore, that is usually how they act like animals by absorbing organic carbon. #5. WebbPhylum Porifera are the lowest multicellular animals belonging to the kingdom Animalia. The word “Porifera” mainly refers to the pore bearers or pore bearing species. Based on the embryological studies, sponges are proved as animals and are classified into a separate Phylum in animals. This phylum includes about 5000 species.
