== == materials get into water by animals waste
Materials removed from the kidneys are urea and water sugar!
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.
Sponges remove nitrogenous waste through a process called diffusion. The waste molecules passively move out of the sponge cells and into the surrounding water, where they are eventually carried away. This allows sponges to efficiently get rid of metabolic waste products from their body.
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.
Water provides structural support to sponges, helping them maintain their shape and enabling them to filter food particles from the water passing through their pores. In addition, water carries oxygen and nutrients to the cells of the sponge and helps in waste removal.
the waste materials are deadcells,excess salts and water
The Vacuole stores food water and waste.
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.
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.
Porous water-absorbing materials are substances that have small pores or holes in their structure, allowing them to soak up and retain water. Examples include sponges, foam, and certain types of fabrics like cotton or wool. These materials are commonly used in products such as diapers, sponges, and water filters.
