the sponge absorbs water, and keeps it in. if you rotate or tilt it, the water will move because of gravity.
The body of a sponge is covered in tiny openings called pores. These pores allow water to flow in and out of the sponge, which helps the sponge filter out food particles and oxygen from the surrounding water.
The body of a sponge helps regulate the flow of water by efficiently channeling it through its pores, allowing for filtration and nutrient intake. At the same time, the sponge controls which materials pass through its pores by utilizing specialized cells to selectively take in beneficial substances while filtering out unwanted particles.
