Detailed explanation-1: -Nitrogenous wastes are the byproduct of metabolic reactions and these are also called metabolic wastes . Urea is the major nitrogenous waste product and it is formed in the liver. Urea is secreted out by the kidney along with uric acid through urine.

Detailed explanation-2: -What is nitrogenous waste in urine? Urea is a nitrogenous waste that is excreted in urine. Ammonia is converted into urea, which is less toxic and requires less water to remove from the body. Urea is created by cells within the liver.

Detailed explanation-3: -Yes, urea is a nitrogenous waste. Excretion: Excretion is the process by which nitrogen-containing waste products of metabolism are eliminated from the body. The main source of nitrogenous waste in humans is Urea excretion is known as ureotelism, and the animals that do so are known as ureotelic animals.

Detailed explanation-4: -1: Nitrogen excretion: Nitrogenous waste is excreted in different forms by different species. These include (a) ammonia, (b) urea, and (c) uric acid.

Detailed explanation-5: -Nitrogen wastes They are ammonia, urea, uric acid, and creatinine. All of these substances are produced from protein metabolism. In many animals, the urine is the main route of excretion for such wastes; in some, it is the feces.
