Natural urea and artificial urea that seep into nature are quickly decomposed by bacteria into ammonia, nitrite ions, and nitrates, and these are substances in the nitrogen cycle. Both uric acid and urea are substances excreted by birds and bats. Urea is found as a natural substance in areas with a dry climate. It was found naturally in 1973 in "Tropin Hill" near Lake Rason in Western Australia, and it was fraught with ammonium phthalate and ammonia phosphate. Urea was the first organic compound produced synthetically from inorganic starting materials, and this undermined the principle of vitalism or vis vitalis in Latin. Urea was discovered as a substance in its own right in 1773 by Hilaire Rouelle. The first to manufacture it was Friedrich Wöhler in 1828 through a chemical reaction process between potassium cyanate and ammonium sulfate; in this way, she paved the way for the branch of organic chemistry, after proving that organic substances can be produced from non-living things and materials.
