During the break-down of amino acids, nitrogen is a waste.
Freshwater protozoans excrete ammonia and mineral salts through the process of diffusion across their cell membrane. This allows waste products to pass out of the cell and maintain proper internal balance.
The formation of urea in the liver helps eliminate toxic ammonia from the body. Ammonia is a byproduct of protein metabolism and can be harmful if it accumulates in high levels. By converting ammonia to urea, the body can safely excrete it through urine, preventing poisoning.
Plants do not excrete urea because they do not produce it as a waste product of metabolism like animals do. Instead, plants excrete waste compounds such as oxygen, water, and organic acids through processes like transpiration and secretion.
Jellyfish excrete from their internal cavity, the coelenteron; some of them also use waste products to feed autotrophic microorganisms, living in mutual symbiosis inside them, in exchange for nutrients like glucose.
They've lost the subsequent enzymes required for catalyzing the synthesis of urea into ammonia.
Tadpoles excrete ammonia and frogs excrete urea
Sharks excrete their urea through their skin. Hence the reason why they have a certain 'ammonia-like' kind of smell.
Animals excrete a variety of substances through the excretory and respiratory systems. Three things they excrete are carbon dioxide, uric acid, and ammonia.
Neither marine nor freshwater fish excrete urine or urea; both marine and freshwater fish excrete nitrogenous waste products as pure ammonia.
Amoebas excrete metabolic waste, mainly in the form of ammonia, through a process called diffusion. Ammonia is released from the cell into the surrounding environment.
Protein is a macronutrient that we get from food. It is made up of Carbon, Hydrogen, Oxygen, and Nitrogen. Proteins are the body's only source of nitrogen. When we ingest a protein containging food we excrete the nitrogen in our urine; it is called urea.
Most aquatic animals, such as fish and marine invertebrates, excrete their nitrogenous waste mainly as ammonia. Ammonia is highly soluble in water and can be easily released through their gills or directly into the environment. This adaptation is beneficial in aquatic environments where water is readily available to dilute and remove toxic ammonia.
Terrestrial arthropods excrete metabolic wastes in the form of uric acid, which is solid and fairly dry. Aquatic arthropods excrete ammonia through gills or other membranes.
Reptiles excrete their nitrogen waste mainly in the form of uric acid, which is a less toxic and more water-conserving waste product compared to ammonia or urea. Uric acid is excreted along with feces in a semi-solid or solid form, minimizing water loss from the body. This adaptation is important for reptiles living in arid environments where water availability is limited.
The nephrids.
Oh, yes. In pretty much the normal fashion. A little string comes out of the back of the fish. Almost all animals excrete wastes. Fishes excrete an ammonia-based waste product.
