Nitrogenous waste excreted by different species are ammonia, urea and uricacid.
Ammonia is a nitrogenous waste with single nitrogen molecule. It requires less energy to produce.Ammonia is very toxic, so excretion of ammonia requires a lot of water. It is seen in aquatic animals like fishes
Urea is a nitrogenous waste with two nitrogen atoms. Urea is less toxic than ammonia. It take less water for excretion than ammonia. It requires more energy to produce. It is seen in mammals
Uricacid is nitrogenous waste molecule with four nitrogen atoms. It requires most energy to produce. It less toxic and requires little water. It is common in birds.
Nitrogenous wastes are metabolic end product which should be excreted out. Waste product must be removed from the body. If it is not removed they will accumulate and interfere with metabolic reaction and cause damage of cells
