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.
It allows nitrogen atoms to continually cycle through the biosphere.
The nitrogen cycle leaves the biosphere primarily through processes like denitrification, where bacteria convert nitrates in the soil back into nitrogen gas (N2), which is then released into the atmosphere. Additionally, nitrogen can exit the biosphere through runoff, where it is carried away by water to other ecosystems or bodies of water. Human activities, such as the burning of fossil fuels and the application of synthetic fertilizers, can also contribute to nitrogen loss by altering natural cycling processes.
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 is lost in the biosphere. Biochemical processes help the Earth rebuild the nitrogen lost. Exchanges of nitrogen are slow and steady.

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.

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.
Biosphere is the entire earth including the interacting living organisms and the abiotic environment that includes the earth, air and water. Typically the subdivisions are (1) populations, (2) communities, and (3) ecosystems that all together make up the biosphere.
