Typically, atmospheric nitrogen gets into the soil by nitrogen-fixing bacteria that are symbiotic with such plants as clover, soybeans and alfalfa. Bacteria in the plant extract nitrogen from the air, and when the plants die, the nitrogen remains in the soil as the plant decays.

Where does nitrogen from the atmosphere go before it enters?
Nitrogen from the atmosphere primarily enters the soil through a process called nitrogen fixation, where certain bacteria convert atmospheric nitrogen (N₂) into ammonia (NH₃) or related compounds. This process occurs in the root nodules of specific plants, like legumes, or in the soil by free-living bacteria. Once in the soil, nitrogen can be taken up by plants or further transformed by other soil microorganisms through processes like nitrification and denitrification. Ultimately, nitrogen becomes part of the food chain as it is absorbed by plants, which are then consumed by animals.
How does nitrogen enter a food web?
Nitrogen enters a food web through the process of nitrogen fixation, where certain bacteria convert atmospheric nitrogen into a form that plants can absorb. Plants then take up this nitrogen through their roots, and it is passed through the food web as animals consume plants and other animals. When organisms die and decompose, nitrogen is released back into the soil for plants to utilize again.
Where does nitrogen go before it enters a plant?
Before nitrogen enters a plant, it typically first undergoes a process called nitrogen fixation, where atmospheric nitrogen (N₂) is converted into ammonia (NH₃) by certain bacteria in the soil or in symbiotic relationships with legumes. This ammonia can then be transformed into nitrates (NO₃⁻) through nitrification, a process carried out by nitrifying bacteria. The resulting nitrates and ammonium ions are taken up by plant roots from the soil, allowing plants to utilize nitrogen for growth and development.
How is soil a nitrogen reservoir?
Soil acts as a nitrogen reservoir by absorbing and storing nitrogen from various sources such as organic matter, fertilizer application, or atmospheric deposition. This stored nitrogen is available for uptake by plants and can be converted into different forms by soil microorganisms, contributing to nutrient cycling in the ecosystem.
What are two ways by which nitrogen can combine and form nitrates?
Nitrogen can combine and form nitrates primarily through two processes: biological nitrification and atmospheric nitrogen fixation. In biological nitrification, soil bacteria convert ammonia (NH3) into nitrites (NO2-) and then into nitrates (NO3-) through a series of oxidation reactions. In atmospheric nitrogen fixation, lightning or certain bacteria convert atmospheric nitrogen (N2) into ammonia, which can subsequently be oxidized into nitrates by soil microorganisms.
What is one way that atmospheric nitrogen enters the soil directly?
Atmospheric nitrogen can enter the soil directly through a process called nitrogen fixation, where specialized bacteria convert atmospheric nitrogen gas into forms that plants can use, such as ammonium or nitrate.
How nitrogen enters the atmosphere?
Typically, atmospheric nitrogen gets into the soil by nitrogen-fixing bacteria that are symbiotic with such plants as clover, soybeans and alfalfa. Bacteria in the plant extract nitrogen from the air, and when the plants die, the nitrogen remains in the soil as the plant decays.
What are different ways by which nitrogen in the air reaches the soil?
Most atmospheric nitrogen (N) exists as N2. Plants cannot use N in this form. The main ways this nitrogen enters soil in a plant usable form include:N fixation by bacteriaLightening caused atmospheric fixationFertilizer manufacturers also use atmospheric N when making N fertilizers.Most of the N is fixated by bacteria, usually in association with a plant. Legumes, like beans, peas and clover, are especially famous for this. The plants provide the bacteria with food and an environment they can live in, and in exchange, they give the plant usable nitrogen compounds.

When organisms die and decompose, nitrogen is released back into the soil for plants to utilize again.
Name the microorganisms which can fix atmospheric nitrogen in the soil?
Examples of microorganisms that can fix atmospheric nitrogen in the soil include certain species of bacteria such as Rhizobium and Azotobacter. These bacteria have the ability to convert atmospheric nitrogen into a form that plants can utilize, ultimately promoting plant growth and soil fertility.
Why farmers prefer to grow bean and peas in nitrogen deficent soil?
They are capable of converting atmospheric nitrogen into nitrogen that can be used by plants. They make the soil better.

Where does the nitrogen from the atmosphere go before enters a plant?
The nitrogen goes into the nodules of the plant.
How do rhizobacteria help plants?
Plants can not use atmospheric nitrogen. Rhizobacteria fixes atmospheric nitrogen into nitrate.plant can utilize nitrate in their metabolism.thus fertility of the soil is maintained.
How does atmospheric nitrogen enter the soil?
Atmospheric nitrogen can enter the soil through a process called nitrogen fixation, where certain bacteria convert nitrogen gas from the air into a form that plants can use. This can occur naturally through biological processes or through human activities such as the use of nitrogen-based fertilizers.
How is nitrogen can be removed from the atmosphere?
Nitrogen fixation is a process where certain bacteria in the soil convert atmospheric nitrogen into a form that plants can use. Plants absorb this fixed nitrogen, and it enters the food chain when animals eat the plants. Additionally, lightning can also fix nitrogen by converting it into nitrogen oxides, which can then be deposited onto the Earth's surface through rainfall.
