It definitely does have an atmospheric component. When organic material is decomposed some of the microorganisms involved in doing this, called denitrifying bacteria, extract the nitrogen from the organic material and put it back in the atmosphere. Other bacteria take nitrogen from the atmosphere and convert it into substances that plants can use. Thus the atmosphere serves as an enormous pool of nitrogen for life. Please see the wikipedia article about the nitrogen cycle for more information.

Outline the major steps in the nitrogyn cycle?
The nitrogen cycle involves several key steps: nitrogen fixation (conversion of atmospheric nitrogen into forms usable by plants), nitrification (conversion of ammonium to nitrite, and then nitrate by bacteria), assimilation (incorporation of nitrogen into plant and animal tissues), ammonification (conversion of organic nitrogen into ammonium), and denitrification (conversion of nitrate back into atmospheric nitrogen by bacteria). These processes help maintain a balance of nitrogen in ecosystems.
What happens during fixation during the nitrogen cycle?
During fixation in the nitrogen cycle, atmospheric nitrogen is converted into ammonia by nitrogen-fixing bacteria. This process makes nitrogen available to plants, which then use it to synthesize proteins and other essential molecules. Fixation is a crucial step in the cycle as it allows organisms to access nitrogen in a form that is usable for growth and development.
Why is phosphorus referred to as a local cycle?
Phosphorus is referred to as a local cycle because it tends to cycle within a specific ecosystem and does not have a significant atmospheric component like carbon or nitrogen. This means that phosphorus primarily moves within soil, water, and living organisms in a localized manner, rather than being transported long distances.
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 is one direct outcome of the nitrogen?
One direct outcome of the nitrogen cycle is the conversion of atmospheric nitrogen into a form that plants can use for growth. This process, called nitrogen fixation, is essential for plant productivity and ecosystem health.
Does the nitrogen cycle have no atmospheric component?
No, the nitrogen cycle has an atmospheric component. Nitrogen gas (N2) in the atmosphere is converted into compounds that can be used by living organisms through processes like nitrogen fixation and denitrification. This atmospheric nitrogen is essential for the functioning of the nitrogen cycle on Earth.
What is the cycle involving the exchange of nitrogen between organisms and the atmosphere?
The nitrogen cycle involves the process of nitrogen fixation by certain bacteria converting atmospheric nitrogen into forms usable by plants, which are then consumed by animals. Decomposers break down organic matter into ammonia and return nitrogen to the soil. Denitrification by bacteria converts nitrates back to atmospheric nitrogen to complete the cycle.
What are the major parts in the nitrogen cycle?
The major parts of the nitrogen cycle include nitrogen fixation (conversion of atmospheric nitrogen into forms usable by plants), nitrification (conversion of ammonium into nitrites and nitrates by bacteria), denitrification (conversion of nitrates back into atmospheric nitrogen), and assimilation (incorporation of nitrogen into plant and animal tissues).
In the nitrogen cycle are there any abiotic conversions of atmospheric nitrogen to biologically active nitrogen such as nitrate or ammonia?
Yes, in the nitrogen cycle, atmospheric nitrogen is converted to biologically active forms through a process called nitrogen fixation. This can occur through abiotic processes, such as lightning or industrial methods, where atmospheric nitrogen is converted to ammonia or nitrate that can be used by plants.
What is the first step of the nitrogen cycle?
The first step of the nitrogen cycle is nitrogen fixation, where certain bacteria convert atmospheric nitrogen gas (N2) into a form that plants can use, such as ammonium (NH4+).
Which component of the carbon cycle and nitrogen cycle captures the energy from the sun?
Plants are a part of the nitrogen and carbon cycles and it captures the energy from the sun.
What organisms are responsible for keeping the nitrogen cycle flowing?
Various bacteria are responsible for carrying out key processes in the nitrogen cycle. For example, nitrogen-fixing bacteria convert atmospheric nitrogen into a form usable by plants. Other bacteria, like nitrifying bacteria, convert ammonium into nitrates, which can then be used by plants. Denitrifying bacteria convert nitrates back into atmospheric nitrogen, closing the cycle.
How does the process of nitrogen fixation contribute to the nitrogen cycle?
Nitrogen fixation is the process by which certain bacteria convert atmospheric nitrogen into a form that plants can use. This contributes to the nitrogen cycle by making nitrogen available for plant growth, which then gets passed on to animals and eventually returns to the soil through decomposition, completing the cycle.
What is the second largest component of atmospheric gases?
Oxygen (~21%) is second to nitrogen (~78%) in the composition of Earth's atmosphere.
How do legumes play a role in the nitrogen cycle?
Legumes play a crucial role in the nitrogen cycle by hosting nitrogen-fixing bacteria in their root nodules. These bacteria convert atmospheric nitrogen into a form that plants can use, enriching the soil with nitrogen and promoting plant growth.
How do bacteria help the nitrogen cycle?
Actually nitrogen exist in the atmosphere in dinitrogen (N2) form and cannot be utilized directly. As such bacteria help in converting atmospheric nitrogen into ammonia which then can be used by the plants.
Outline the major steps in the nitrogyn cycle?
The nitrogen cycle involves several key steps: nitrogen fixation (conversion of atmospheric nitrogen into forms usable by plants), nitrification (conversion of ammonium to nitrite, and then nitrate by bacteria), assimilation (incorporation of nitrogen into plant and animal tissues), ammonification (conversion of organic nitrogen into ammonium), and denitrification (conversion of nitrate back into atmospheric nitrogen by bacteria).
