Detailed explanation-1: -The Porifera are primarily filter feeders, utilizing food particles suspended in the water and captured by the choanocytes. Food particles consist essentially of bacteria, other microorganisms, and particles of organic debris; sponges also probably absorb dissolved organic substances.
Detailed explanation-2: -Today, filter feeders like clams, sponges, krill, baleen whales, fishes, and many others fill the ocean, spending their days filtering and eating tiny particles from the water.
Detailed explanation-3: -Clams Clean the Water by Filter Feeding Suspended particles in the water are captured by the gills and moved to the mouth for ingestion. The cleared water is then ejected from the excurrent siphon. By this very act of feeding, clams filter phytoplankton (microscopic algae or plants), microorganisms, and detritus.
Detailed explanation-4: -filter feeding, in zoology, a form of food procurement in which food particles or small organisms are randomly strained from water. Filter feeding is found primarily among the small-to medium-sized invertebrates but occurs in a few large vertebrates (e.g., flamingos, baleen whales).
