Unlike mammals (which create urea) birds turn nitrogenous wastes into uric acid.
This conserves water - as uric acid can be excreted as the thick white substance which is familiar in bird droppings. For mammals, urine consists of urea dissolved in water.
uric acid
Uric acid is a nitrogenous waste that requires the least amount of water to excrete because it is mostly insoluble in water. This makes it advantageous for animals in dry environments or those with limited access to water. Examples of animals that excrete uric acid include birds and reptiles.
Tadpoles excrete ammonia and frogs excrete urea
It excretes it into the ALLANTOIS GLAND.
Birds do not urinate like mammals do. They excrete nitrogenous waste in the form of a semisolid waste called uric acid, which is combined with their feces and expelled together. This helps birds conserve water and maintain a lighter body weight for flight.
All of the organs mentioned excrete waste. The lungs excrete carbon dioxide, the large intestine excretes solid waste, and the kidneys excrete nitrogenous waste.
Pisces fish excrete waste through their gills and kidneys. Waste products such as ammonia are released into the water through their gills, while the kidneys help filter out and excrete other waste materials.
Excrete more frequently
cos their food has very little nitrogen in it and they need it all
Animals that excrete in the form of urea nitrogenous waste derived from amino-acid catabolism
Neither marine nor freshwater fish excrete urine or urea; both marine and freshwater fish excrete nitrogenous waste products as pure ammonia.
No, swordfish do not excrete through their skin. They primarily excrete waste through their kidneys and gills, similar to other fish. The kidneys filter waste products from the bloodstream, while the gills help eliminate ammonia and other nitrogenous wastes.
