Nitrogen is an essential element for life on Earth. It is a key component of proteins, nucleic acids and other important biological molecules. The largest reservoir of nitrogen is found in the atmosphere, where it makes up 78% of the total volume.
Nitrogen is also found in the soil, where it is released by bacteria and other microorganisms as they break down organic matter. This nitrogen is available to plants, which use it to build proteins and other essential molecules. Nitrogen is also found in a wide variety of minerals, such as nitrates, nitrites, and ammonium.
In the ocean, nitrogen is found in the form of dissolved nitrogen gas, nitrate and ammonium, as well as in the form of organic nitrogen. This nitrogen is released into the water by phytoplankton, and is then taken up by other organisms.
Nitrogen can also be found in the form of nitrates and nitrites in groundwater, which is an important source of nitrogen for plants. Nitrates and nitrites are also found in the air, as a result of nitrogen oxide emissions from factories and other sources.
Nitrogen cycles between the atmosphere, land, and ocean, and is essential for all life on Earth. The largest reservoir of nitrogen is in the atmosphere, where it makes up 78% of the total volume. Nitrogen is also found in the soil, ocean, and groundwater, and is essential for the growth of plants and other organisms. It is released into the environment by bacteria and other microorganisms, and taken up by plants and other organisms. Nitrogen is also released into the environment as a result of nitrogen oxide emissions from factories and other sources.
