How much deeper will the ocean be without sponges?
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.
