Detailed explanation-1: -In order obtain food, sponges pass water through their bodies in a process known as filter-feeding. Water is drawn into the sponge through tiny holes called incurrent pores.

Detailed explanation-2: -As sponges don’t have mouths, they must feed by some other method. Sponges have tiny pores in their outer walls through which water is drawn. Cells in the sponge walls filter food from the water as the water is pumped through the body and out other larger openings.

Detailed explanation-3: -Instead of having a mouth, sponges bodies feature tiny pores called Ostia through which water is sucked. Cells in the sponge walls then filter the food that is present in the water as it is pumped out of the body through the osculum.

Detailed explanation-4: -Sponges are a type of suspension feeder, but because they actively pump water through their bodies, they are more specifically called filter feeders. Other examples of filter feeders include clams and mussels. Some suspension feeders, like corals, do not actively pump water through their bodies.

Detailed explanation-5: -Filter feeding is a method some animals use to feed where the animal finds their meal by moving through the water, or taking advantage of water moving by them, and extracting small pieces of food and other particles from the water.
