What is the role of nitrogen fixing bacteria?
Nitrogen-fixing bacteria play a crucial role in the nitrogen cycle by converting atmospheric nitrogen into a form that plants can use for growth. This process helps to replenish soil nutrients, promoting plant health and ecosystem sustainability.
What does an increase in nitrogen in the atmosphere mean?
It depends. There could be a factory in the vicinity that is pumping nitrogen into the air because of the chemical processes involved. There could even have been an explosion somewhere near increasing the level of nitrogen in the atmosphere. But nitrogen is, of course, also an intrinsic element in the socalled nitrogen cycle in nature, and any inbalance in this regard -- the freeing of more or less nitrogen than could be considered "normal" from its fixations in the soil or elsewhere -- could be a clear sign that something is wrong with the environment.
Which are the most abundant gases in the atmosphere at sea level?
These gases are: nitrogen (78,084 %), oxygen (20,9476 %), water vapors (variable concentration), argon (0,934 %), carbon dioxide (0,0314).
What is the valence level of nitrogen?
the valency of nitrogen is 3symbol:Natomic mass:14
What level of biologic organization is represented by nitrogen cycle in nature?
The nitrogen cycle represents the ecosystem level of biological organization. It involves interactions between various biotic components, such as plants, bacteria, and animals, and abiotic components like soil and atmosphere, illustrating how nitrogen is recycled in nature. This cycle is crucial for maintaining soil fertility and supporting life, showcasing the interconnectedness of organisms within their environment.
Why does the nitrogen level in the atmosphere is higher than the oxygen level?
Because due to the over pollution and cutting down the tree's level of Oxygen is decreasing .The level of Nitrogen always remains constant in the atmosphere . The level of Nitrogen doesn't' depend on the level of the Oxygen level.
What is the main ingredient in air?
If by "main ingredient", you mean the substance that comprises the largest percentage of the volume of the earth's atmosphere, the answer is Nitrogen, specifically the N2 molecule, comprising about 78.1% of the volume (and 75.3% of the weight) of the earths' atmosphere.
What is the role of nitrogen-fixing bacteria?
they help balance the level of nitrogen in the soil and atmosphere.
What is Earths weather atmosphere?
Most kinds of weather occurs in the troposphere, the lowest level of the atmosphere.
What occurs when a high level of charged particles outside the earths atmosphere manages to penetrate the atmosphere?
auroras

What helps to maintain the current level of nitrogen in Earth's atmosphere?
Mainly the fact that nitrogen is largely inert.
What is the lowest level of the earths atmosphere called?
The lowest level of the Earth's atmosphere is called the troposphere. It is where most weather phenomena occur and contains approximately 75% of the atmosphere's mass.
Why has the nitrogen level in the atmosphere kept constant over time?
The absolute amount of nitrogen in the atmosphere has kept constant over time because it is not a gas that reacts readily with other elements - it is relatively inert. However, the relative level of nitrogen in Earth's atmosphere has changed over time as the atmosphere was "terraformed" by the life evolving on the planet. For instance in the Cretaceous times the atmosphere was much richer in Oxygen (30%) than today (20%) which means that then the %Nitrogen was 70% rather than 80%.
How did the level of nitrogen gas increase in the atmosphere?
The level of nitrogen gas in Earth's atmosphere increased over time due to the process of nitrogen fixation, where certain bacteria convert atmospheric nitrogen into forms that can be utilized by plants. Human activities like the burning of fossil fuels and industrial agriculture have also contributed to the increase in atmospheric nitrogen levels through the release of nitrogen compounds.
