👉 Nitrification is a biological process in which nitrogenous compounds are converted into nitrate (NO3-). It occurs when oxygen from air is used to convert carbon dioxide and water molecules into nitrous oxide, ammonia, and hydrogen. This process is crucial for the growth of many organisms and plays a role in several important biochemical reactions, including those that occur within cells during photosynthesis, respiration, and the synthesis of organic compounds through various metabolic pathways. Nitrification is an essential step in
