Nitrogen has been present forever. It is the most abundant gas. Industrial revolution has changed it's concentration.
What else can I help you with?
How are nitrates changed back into nitrogen?
Nitrates can be changed back into nitrogen through a process called denitrification. This process is carried out by denitrifying bacteria in the soil, which convert nitrates into nitrogen gas under anaerobic conditions. This nitrogen gas is then released back into the atmosphere.
What are 2 ways that nitrogen can be removed from the atmosphere?
Nitrogen can be removed from the atmosphere through the process of nitrogen fixation, where certain bacteria convert atmospheric nitrogen into forms that plants can use. Nitrogen can also be removed through lightning strikes, which can combine nitrogen molecules with oxygen to form nitrogen oxides that are washed out of the atmosphere by rain.
What happen to a nitrogen atom in the atmosphere that captures a neutron?
When a nitrogen atom in the atmosphere captures a neutron, it may become a radioactive isotope of nitrogen called nitrogen-14. This process can occur in the upper atmosphere, leading to the creation of carbon-14 through a series of nuclear reactions.
What does bacteria do with nitrogen from the atmosphere?
Bacteria can convert atmospheric nitrogen into a usable form for plants through a process called nitrogen fixation. This process is important for the nitrogen cycle, as it allows plants to absorb essential nutrients.
What the process that releases nitrogen gas into the atmostosphere?
The process that releases nitrogen gas into the atmosphere is called nitrogen fixation. This process involves converting atmospheric nitrogen into forms that plants can use, either through natural processes like lightning or through human activities like industrial manufacturing. Once nitrogen is fixed, it can be taken up by plants and eventually returned to the atmosphere through processes like denitrification.
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.
What process has changed the percentages of nitrogen in the atmosphere?
Nitrogen has been present forever. It is the most abundant gas. Industrial revolution has changed it's concentration.
How are nitrates changed back into nitrogen?
Nitrates can be changed back into nitrogen through a process called denitrification. This process is carried out by denitrifying bacteria in the soil, which convert nitrates into nitrogen gas under anaerobic conditions. This nitrogen gas is then released back into the atmosphere.
What is a nitrogen-fixing?
nitrogen fixing is a process in which atmosphere nitrogen converted into ammonia.
What is a nitrogen fixing?
nitrogen fixing is a process in which atmosphere nitrogen converted into ammonia.
What percentage of nitrogen is fixed by nitrogen fixing bacteria?
Around 70-80% of nitrogen in the atmosphere is fixed by nitrogen fixing bacteria through a process called nitrogen fixation. This converted nitrogen is then made available for use by plants and other organisms in the environment.
Water carbon and nitrogen are released back into the atmosphere during what?
Water vapor is released back into the atmosphere through the process of evaporation. Carbon is released back into the atmosphere through the process of respiration and combustion. Nitrogen is released back into the atmosphere through the process of nitrogen fixation by bacteria.
What is the name of the process that returns nitrogen into the atmosphere?
The process that returns nitrogen to the atmosphere is called denitrification. This biological process is carried out by certain bacteria that convert nitrates and nitrites in the soil back into nitrogen gas (N₂), which is then released into the atmosphere. Denitrification is a crucial part of the nitrogen cycle, helping to maintain the balance of nitrogen in ecosystems.
What is the process which nitrogen returns to atmosphere?
Denitrification
If you say that a certain process fixes nitrogen what does this mean which natural process in the atmosphere fixes nitrogen?
Lightning.
How does nitrogen get from organisms back into the atmosphere?
Nitrogen is returned to the atmosphere through the process of denitrification, where bacteria convert nitrates in the soil back into nitrogen gas. This process completes the nitrogen cycle as nitrogen is released back into the atmosphere as a gas.
By what process is nitrogen returned to the atmosphere by bacteria?
Nitrogen is returned to the atmosphere by a process called denitrification, where certain bacteria convert nitrates in the soil back into nitrogen gas which is then released into the air. This helps maintain the balance of nitrogen in the environment cyclically.
