It is a kind of marine organism that is not mobile. They are rigid structures found attached to a place. They are large mass of microscopic simple animals living together.
No, a sea sponge is a whole different group of animals that are not closely related at all to fish.
yes,because the source of food of the sponge is in water
yes they are. a sea animal lives in the sea and sponges live in the sea

By providing a habitat
the sponges
There are thousands of marine animals in the ocean. Dolphins, Sharks, Sea turtles,Sponges, and many types of fish. I'm pretty sure that plankton floats in the currents and animals such as sponges eat them.
Freshwater sponges are delicate in structure, growing as encrusting or branching masses. They usually appear greenish because of the algae that live on them. Freshwater sponges may attain a volume of more than 2,500 cubic centimeters (150 cubic inches). Marine sponges are natural bath sponges (with living cells removed) that we all are familiar with. They actually are the oldest and simplest animals that have been living on earth for millions of years. Marine sponges are filter-feeding animals because all adult sponges are sessile and can't move around benthic surface. Marine sponges have no true tissues or organs, just constructed with layers of cells even without nervous system. Marine sponges come in different but striking colors, bright red, purple, yellow, and brown, etc. These colors and some are toxic as well may help them defend from sponge eating invertebrates and some fishes. Some other small marine organisms, fishes, and microscopic organisms often call marine sponges their homes. There are no terrestrial sponges because they are filter feeders obtain from water particles.

No, kitchen sponges nowadays are usually made from cellulose or synthetic plastics. Real marine sponges were used by early Europeans to also clean, but it was stopped due to overfishing that almost brought the sponges to extinction.
