== == materials get into water by animals waste
None. Everything you lose (water & salt) is essential.
"clean" water and "waste" water in a sponge are all the same. Their bodies allow constant flow of water, there is no beginning and end to a sponge; thus technically waste water leaves a sponges body through its many pores.
Materials removed from the kidneys are urea and water sugar!
the waste materials are deadcells,excess salts and water
Sham wow, sponges, rags, basically any common household materials.
The Vacuole stores food water and waste.
the answer is "yes" because sponges are attached to hard surfaces underwater, and they are well adapted to their watery life. moving water currents carry food and oxygen to them and take away the sponges' waste products.
Excess water is removed from undigested food waste in the large intestine. This waste, called feces, is then stored in the rectum until expelled through the anus.
Sponges (poriferans) are very simple animals that live permanently attached to a location in the water - they are sessile as adults. There are from 5,000 to 10,000 known species of sponges. Most sponges live in salt water - only about 150 species live in fresh water. Sponges evolved over 500 million years ago. The body of this primitive animal has thousands of pores which let water flow through it continually. Sponges obtain nourishment and oxygen from this flowing water. The flowing water also carries out waste products.

It stores food, water, and waste materials.
