The nitrogen cycle is a repeated pattern in nature because it is an essential process for the availability and recycling of nitrogen, which is a vital element for living organisms. Nitrogen exists in various forms in the environment, such as atmospheric nitrogen gas, organic nitrogen in plants and animals, and inorganic nitrogen in soil and water. The nitrogen cycle involves a series of complex biological and chemical reactions that transform these different forms of nitrogen into usable compounds and return them back to the environment. This cycle is repeated continually to ensure a steady supply of nitrogen for plants, which are the primary producers and the foundation of the food chain. Thus, the nitrogen cycle is a crucial and continuous process that maintains the balance and sustainability of ecosystems.
