Urea is less toxic than ammonia.
The kidneys are responsible for excreting water, excess fats, and various catabolic wastes from the body through the production of urine.
Nephridia remove metabolic wastes, such as nitrogenous compounds (e.g., ammonia), from the body by filtering them from the coelomic fluid and releasing them outside the body.
The three main nitrogenous wastes in animals are ammonia, urea, and uric acid. Ammonia is the most toxic and soluble in water, requiring a high volume of water for its excretion. Urea is less toxic and requires a moderate amount of water for excretion. Uric acid is the least toxic and least soluble, needing very little water for excretion.
Excretion of nitrogenous wastes is critical because these wastes are toxic to the body if they accumulate. By excreting nitrogenous wastes, the body maintains a balance of these compounds, preventing toxic build-up that can lead to severe health issues and even death. Proper excretion also helps regulate fluid and electrolyte balance in the body.
Firstly there is more than one metabolic reaction, the term simply means pathways of reaction that build up and/or breakdown complex molecules. So all cells have many metabolic pathways each with many reactions and many waste products. For this reason the question is unanswerable.
Urine is the bodies method of excreting excesswater and dissolved wastes.

The organs that are involved in the excretion of the digestive wastes are lungs, kidneys and the sweat glands in the skin. Hope this helped.
The kidney is responsible for removing waste products from the body by filtering blood and excreting waste materials in the form of urine.

Common nitrogenous wastes in urine are: urea, uric acid and ammonia.
The advantages of wastes segregation,it is easily to collect by the wastes collectors and you will know what to do in each wastes that you have been collected
Converting ammonia to bicarbonate ion seems like something an alchemist would do. Kidneys (ours, at least) convert nitrogenous wastes (things like ammonia or compounds with an amine group attached - R-NH2) to urea, which is far less toxic than ammonia.

Urea is the less toxic in nature among the nitrogenous wastes where as Ammonia is 100,000 times toxic than urea.
