What process has changed the percentage of nitrogen in the earth's atmosphere?
The process that has changed the percentage of nitrogen in the Earth's atmosphere is biological nitrogen fixation, where certain bacteria convert nitrogen gas into a form that plants can use. This has led to an increase in nitrogen levels over time.
Where does nitrogen originate from in the Earth's ecosystem?
Nitrogen originates from the Earth's atmosphere, where it makes up about 78 of the air we breathe. This nitrogen is converted into a usable form by certain bacteria in the soil, which plants then absorb and incorporate into their tissues. This process is known as nitrogen fixation.
Is nitrogen cycled through the earth's atmosphere?
Yes, nitrogen is cycled through the Earth's atmosphere through a process known as the nitrogen cycle. This cycle involves various processes such as nitrogen fixation by bacteria, denitrification, and nitrification, leading to the conversion of nitrogen into different forms that can be used by living organisms.
How does atmospheric nitrogen become usable on earth?
Atmospheric nitrogen is transformed into a usable form through a process called nitrogen fixation, where certain bacteria convert nitrogen gas into ammonia. This ammonia can then be taken up by plants and used to produce proteins. Additionally, lightning can also convert nitrogen gas into reactive nitrogen compounds that can be absorbed by plants.
What is the main reservoir of nitrogen in the biosphere?
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.
What will allow nitrogen fixation to occur?
well mainly it will cause an earth explosion everyone and everything will die.

Is nitrogen gas nonrenewable?
No, nitrogen gas is considered a renewable resource because it is continuously replenished in the Earth's atmosphere through natural processes such as nitrogen fixation by lightning, bacteria, and plants.
Is nitrogen cycled through the earth's atmosphere?
Yes, nitrogen is cycled through the Earth's atmosphere through a process known as the nitrogen cycle. This cycle involves various processes such as nitrogen fixation by bacteria, denitrification, and nitrification, leading to the conversion of nitrogen into different forms that can be used by living organisms.
How is nitrogen fixation carried out?
Nitrogen fixation is the process by which nitrogen is taken from its relatively inert molecular form (N2) in the atmosphere and converted into nitrogen compounds useful for other chemical processes (such as, notably, ammonia, nitrate and nitrogen dioxide).

What are fixation and deposition part of?
Fixation and deposition are part of the process of nutrient cycling in ecosystems. Fixation involves converting atmospheric nitrogen into a usable form by certain organisms, while deposition involves the accumulation of nutrients, such as nitrogen and phosphorus, on the surface of the Earth through natural processes like precipitation. Together, these processes contribute to the availability of essential nutrients for plants and other organisms in the ecosystem.
How is nitrogen cycle like water cycle?
Both the nitrogen cycle and water cycle involve the movement of a key substance through different forms and locations in the environment. In the water cycle, water is cycled through various processes like evaporation, condensation, and precipitation. Similarly, in the nitrogen cycle, nitrogen is cycled through processes like nitrogen fixation, nitrification, and denitrification. Both cycles are essential for maintaining ecosystem balance and supporting life on Earth.
Why is there so much nitrogen in the air?
Nitrogen makes up about 78% of Earth's atmosphere because it is an inert gas that is not easily reactive with other elements. It is continuously cycled through the environment by processes like nitrogen fixation and denitrification.
