atmosphere as N2 gas
Most of the nitrogen in the biosphere is located in the atmosphere, where it exists as a gas (N2). Nitrogen gas makes up about 78% of Earth's atmosphere.
The main reservoir of nitrogen in the biosphere is the atmosphere. Nitrogen gas (N2) makes up about 78% of Earth's atmosphere. Nitrogen is cycled through the biosphere by processes like nitrogen fixation, nitrification, and denitrification.
nitrogen fixing bacteria
Nitrogen is lost in the biosphere. Biochemical processes help the Earth rebuild the nitrogen lost. Exchanges of nitrogen are slow and steady.

Three nitrogen-containing nutrients in the biosphere are proteins, nucleic acids (DNA and RNA), and amino acids. Nitrogen is an essential component of these molecules and is crucial for the growth and development of living organisms.
Humans add nitrogen to the biosphere primarily through the use of synthetic fertilizers in agriculture, which then gets taken up by plants and enters the food chain. Additionally, industrial processes involving nitrogen, such as the production of ammonia, also introduce nitrogen into the environment.
Nitrogen is released to the abiotic parts of the biosphere through decomposition of organic matter and nitrogen-fixing bacteria in the soil. When organisms die, their nitrogen-containing molecules are broken down by decomposers, releasing nitrogen back into the environment. Additionally, nitrogen-fixing bacteria can convert atmospheric nitrogen into a form that plants can use, further cycling nitrogen through the ecosystem.
all life-forms are located in the biosphere
The majority of nitrogen in the biosphere is stored in the atmosphere, where it makes up about 78% of the air we breathe. Additionally, nitrogen is also found in soil in various forms, such as organic matter, inorganic compounds, and living organisms.
