How does nitrogen get in the earths atmosphere?
Nitrogen is present in the Earth's atmosphere primarily as a result of volcanic eruptions and geologic activities releasing nitrogen from rocks. Additionally, nitrogen-fixing bacteria in the soil convert nitrogen from the air into a form that plants can use, which can eventually be released back into the atmosphere through various processes.
What is the percentage of nitrogen present on Earth?
about 70 percent of the atmosphere is nitrogen
Which area on the illustration represents the largest reservoir of nitrogen on earth?
The illustration that represents the largest reservoir of nitrogen on earth should display the atmosphere. The atmosphere of earth contains around 78.09 % nitrogen.
How much of the earth atmosphere is nitrogen?
Approximately 78% of the Earth's atmosphere is made up of nitrogen.
What contains 78 percent nitrogen?
The Earth's atmosphere. Almost 22% of the remaining gas is oxygen, put a very small portion is made up of other gases, called trace gases.
How organisms put nitrogen back into the ecosystem?
nitrogen fixation. look it up
What of bacteria put nitrogen back into the air?
nitrites
How does dead organism return inorganic nitrogen back to earth?
How do dead organism return inorganic back to the earth
What kind of bacteria put nitrogen bacteria put nitrogen back into the air?
Nitrogen-fixing bacteria, such as Rhizobium and Azotobacter, convert atmospheric nitrogen into a form that plants can use. This process helps in replenishing the soil with nitrogen and plays a crucial role in the nitrogen cycle.

What is the role of volcanic eruption in nitrogen fixation?
they put carbon dioxide back in the atmosphere
How do you get nitrogen on earth?
Nitrogen is fixed
What planet is Its atmosphere is mostly nitrogen?
Planet Earth - about 80%.
What is the percentage of nitrogen in the Earth's atmosphere?
The percentage of nitrogen in the Earth's atmosphere is about 78.
What is the percentage of nitrogen present on Earth?
about 70 percent of the atmosphere is nitrogen
What are the ways nitrogen enters and leaves the atmosphere?
Nitrogen enters the atmosphere primarily through volcanic eruptions and the release of gases from the Earth's crust. It also comes from biological processes, such as denitrification, where bacteria convert nitrates in soil back into nitrogen gas. Nitrogen leaves the atmosphere mainly through nitrogen fixation, where certain bacteria convert atmospheric nitrogen into ammonia, and through processes like precipitation, where nitrogen compounds are deposited back to the Earth's surface. Additionally, human activities, such as burning fossil fuels and industrial processes, can also influence nitrogen levels in the atmosphere.
Is nitrogen the main part of earth's atmosphere?
Yes, Earth's atmosphere is about 78% nitrogen.
