Nitrogen is removed from the atmosphere primarily through the process of nitrogen fixation. This occurs when certain bacteria, often found in soil or root nodules of legumes, convert atmospheric nitrogen (N₂) into ammonia (NH₃), which can be utilized by plants. Additionally, lightning can also contribute by converting nitrogen gas into nitrates, which fall to the ground with rain. Finally, industrial processes, such as the Haber-Bosch method, also fix nitrogen for agricultural use.
The nitrogen cycle begins with nitrogen fixation, where atmospheric nitrogen (N₂) is converted into ammonia (NH₃) by nitrogen-fixing bacteria or through lightning. Next, nitrification occurs, where ammonia is oxidized into nitrites (NO₂⁻) and then nitrates (NO₃⁻) by nitrifying bacteria. Plants absorb nitrates for growth, and when animals consume these plants, nitrogen enters the food chain. Finally, denitrification occurs, where denitrifying bacteria convert nitrates back into N₂, releasing it back into the atmosphere and completing the cycle.
Nitrogen makes up about 80% of the Earth's atmosphere.
The Earth has an atmosphere of 78% nitrogen (and 21% oxygen).
composition of dry atmosphere by volume..... 78.09% nitrogen
Planet Earth - about 80%.
The nitrogen cycle begins with nitrogen fixation, where atmospheric nitrogen (N2) is converted into ammonia (NH3) by nitrogen-fixing bacteria in the soil or root nodules of certain plants. This ammonia can then be transformed into nitrites (NO2-) and nitrates (NO3-) through nitrification, allowing plants to absorb these forms of nitrogen. When plants and animals die or excrete waste, decomposers break down organic matter, returning nitrogen to the soil as ammonium (NH4+). Finally, denitrification occurs, where denitrifying bacteria convert nitrates back into atmospheric nitrogen (N2), completing the cycle.
Nitrogen is used in the atmosphere by.....
N2 molecules break apart via nitrogen-fixing bacteria. Other living entities such as plants and animals ingest nitrogen in nitrate-containing compounds. Organic matter decays via decomposers. N2 is formed via denitrifying bacteria.
98% of Titan's atmosphere is Nitrogen

1. Nitrogen molecules are split apart 2. Nitrogen moves from soil to plant material 3. Dead animals decompose 4. Gaseous nitrogen released
The form of nitrogen that is beneficial for the atmosphere is nitrogen gas (N2).
Nitrogen makes up about 80% of the Earth's atmosphere.
nitrogen fixation, denitrification, nitrification, amonification are the for steps of the nitrogen cycle.
it doesn't, it only removes soil nitrogen
Nitrogen accounts for 78% of the atmosphere.
The Earth has an atmosphere of 78% nitrogen (and 21% oxygen).
