The Nitrogen Cycle is a continuous process of nitrogen moving around throughout an ecosystem.
It is an important part of many cells and processes such as amino acids, and proteins. It is also needed to make chlorophyll in plants, which is then used during photosynthesis so plants can produce food and energy.
In most ecosystems nitrogen is primarily stored in living and dead organic matter. Then the organic nitrogen is converted into inorganic forms which then re-enter the cycle because of decomposition. Next, the decomposes in the soil chemically modify the nitrogen found in the organic matter from ammonia to ammonia salts. These salts are then carried out by a variety of bacteria, amniocenteses, and fungi. Which then we consume
We couldn't live without Nitrogen. In fact about 80% of the air in the atmosphere is Nitrogen.
