Detailed explanation-1: -Nitrogenous wastes are formed from the metabolism of protein in the liver. The proteins are metabolized or broken down to form amino acids which further break down to form the nitrogenous waste. The nitrogenous wastes include, urea, uric acid, ammonia, etc.

Detailed explanation-2: -The urea is the primary nitrogenous waste formed by the breakdown of amino acids in the body. Mammals are the main producers of urea as they secrete urea as the major nitrogenous waste product in the body. These animals are called ureotelic animals.

Detailed explanation-3: -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.

Detailed explanation-4: -Ammonia is produced from leftover amino acids, and it must be removed from the body. The liver produces several chemicals (enzymes) that change ammonia into a form called urea, which the body can remove in the urine. If this process is disturbed, ammonia levels begin to rise.

Detailed explanation-5: -Proteins are made up of amino acids. When these proteins are broken down, nitrogenous wastes are produced. This waste is produced in the form of ammonia. This ammonia is converted to urea and it is excreted out of our body.
