Sponges, belonging to the phylum Porifera, do not have true tissues or organs, which differentiates them from more complex animals. They lack a nervous system, digestive system, and circulatory system, relying instead on the flow of water through their porous bodies for nutrient intake and waste removal. Additionally, sponges do not possess specialized structures like fins, limbs, or a centralized body plan, which are found in many other animal groups.
No sponges arent mollusks. Mullusks are in their own phylum 'mollusca' and spongers are a part of their own phylum called 'porifera'

Sea sponges are a part of the marine biome. They are even found in the disphotic zone of the ocean, also known as the Twilight Zone.
Sponges displace the ocean's water, and the water that they do "suck up" becomes part of their volume, and thus has no effect on the depth of the oceans. When you remove sponges, they will no longer displace water in the ocean, so the ocean will actually be shallower.
Sponges provide many kinds of information:Studying different kinds of animals is just interesting because they're so different from usStudying how sponges live teaches you some of the ways that our bodies stay aliveStudying how sponges survive in the ocean teaches you to respect and care for the ocean and the plants and animals that live thereStudying how sponges are part of the ecosystem teaches you that every living thing is important

No, they are carbon-based as is all life on earth (as we know it). They do have silica as part of their body, but the main part is carbon.
Animals. The part that we think of as "sponge" is their skeleton.
Sponges are asymmetrical, although a few species have nearly radial symmetry.
