Sponges do not have a mouth, a neural system or even any sensing organs. Still they have a variety of specialized cells, performing different tasks like pumping water, extracting and digesting particles from the water. A sponge may filter 10.000 - 20.000 times its own volume every day. Tiny hairs shimmer continuously to pump water through its internals. Sponges are responsible for the very important task of dissolving solid calcium and thereby enable mussels and others to reuse it to build their shells.
Jellies have one bodily orifice and they use it for everything.
The mouth is located on the lower surface (the bottom) of a jellyfish.
Since jellyfish float in the water with their tentacles hanging down, you would say they put food into their mouth.

Most jellyfish live near the mouth of Chesapeake Bay
A jellyfish takes food in through its mouth which is located on the underside if its bell. Food is digested in a sac-like structure called a coelenteron or gastrovascular cavity. Waste material is passed out through the mouth.
