What process carried out by microorganisms inon the soil that releases nitrogen back into the atmosphere?
The process carried out by microorganisms in the soil that releases nitrogen back into the atmosphere is called denitrification. During this process, certain bacteria convert nitrates (NO3-) and nitrites (NO2-) back into nitrogen gas (N2) or, to a lesser extent, nitrous oxide (N2O), which is then released into the atmosphere. This process is essential for maintaining the nitrogen cycle, helping to regulate nitrogen levels in the environment.
Where does the nitrogen from animals or plants go when they die?
When animals or plants die, the nitrogen in their tissues is broken down by decomposers like bacteria and fungi. This process releases nitrogen back into the soil in the form of ammonium. Some of this nitrogen can be taken up by plants through their roots to use for growth, while excess nitrogen can be converted into nitrate and enter the groundwater system.
The conversion of nitrates back into free nitrogen by bacteria in the soil is?
called denitrification. This process releases nitrogen gas back into the atmosphere, completing the nitrogen cycle. Denitrification occurs under anaerobic conditions where bacteria use nitrates as an alternative electron acceptor in the absence of oxygen.
Nitrogen-fixing bacteria in soil turns nitrogen gas into?
they turn the nitogen gas into the nitrates and nitrites essential for the soil
Bacteria return nitrogen to the soil by which process?
Bacteria return nitrogen to the soil through a process called nitrogen fixation, where they convert atmospheric nitrogen into a form that plants can use. This allows plants to obtain the necessary nitrogen for their growth and, in turn, enriches the soil with nutrients.

What role does the denitrification play in the nitrogen?
When organisms die, decomposers return nitrogen to the soil as ammonia. The ammonia may be taken up again by producers. Other soil bacteria convert nitrates into nitrogen gas in a process called denitrifrication. this process releases nitrogen into the atmosphere once again.
Process in which nitrogen is released into the air and soil?
Nitrogen fixation is the process by which nitrogen gas is converted into a form that plants can use, predominantly by nitrogen-fixing bacteria. Denitrification is the process by which nitrogen is released from soil back into the atmosphere in the form of nitrogen gas.
Process in which soil bacteria convert nitrogen compounds in soil back into biomolecules used for energy by living things is?
The process in which soil bacteria convert nitrogen compounds in soil back into biomolecules used for energy by living things is called nitrogen fixation. During this process, certain bacteria convert atmospheric nitrogen into a form that plants can use to grow. This process is essential for the cycling of nitrogen in ecosystems.

How do nitroge returned to the atmosphere?
Nitrogen returns to the atmosphere primarily through the process of denitrification, where anaerobic bacteria convert nitrates in the soil back into nitrogen gas (N₂) or nitrous oxide (N₂O). This gas is then released into the atmosphere. Additionally, the decomposition of organic matter also contributes to this process, as it releases nitrogen compounds back into the soil, which can subsequently be denitrified. Overall, these natural processes help maintain the nitrogen cycle and balance atmospheric nitrogen levels.
The conversion of nitrates back into free nitrogen by bacteria in the soil is?
called denitrification. This process releases nitrogen gas back into the atmosphere, completing the nitrogen cycle. Denitrification occurs under anaerobic conditions where bacteria use nitrates as an alternative electron acceptor in the absence of oxygen.
How do you separate nitrogen from soil?
Bacteria in the soil called nitrogen-fixing bacteria go through a process called nitrogen-fixation which allows nitrogen to enter the atmosphere
What are The three ways that nitrogen is made available to plants?
Nitrogen fixation by bacteria in the soil or root nodules of leguminous plants converts atmospheric nitrogen into a form that plants can use. Decomposition of organic matter releases nitrogen back into the soil as ammonium. Application of nitrogen-containing fertilizers can supplement soil nitrogen levels for plant growth.
Nitrogen-fixing bacteria in soil turns nitrogen gas into?
they turn the nitogen gas into the nitrates and nitrites essential for the soil
How is soil affected by the process of biological decomposition?
Biological decomposition breaks down organic matter in the soil into simpler compounds that can be used by plants. This process releases nutrients such as nitrogen and phosphorus into the soil, improving its fertility. Decomposition also helps to improve soil structure by increasing its porosity and water-holding capacity.
When there is not enough nitrogen in the atmosphere for plants how do the plants get it?
Plants do not actually get their nitrogen from the atmosphere. They get it in compounds in the soil through their roots. Some plants form symbiotic relationships with bacteria in the soil. The bacteria draw nitrogen from the air and form nitrogen compounds. The plants can then use the nitrogen.
