Plants absorb nitrate compounds from soil through their root hairs, which are outgrowths of the trichoblast cells in the roots.
Most plants are not able to use nitrogen as such (N2), though some, including legumes and casuarinas, supply water and food to symbiotic nitrogen-fixing bacteria in specialised root nodules, and these fix nitrogen to nitrate which they supply to the plants.
Plants cannot use nitrogen directly from the atmosphere. Instead, specialized bacteria called nitrogen-fixing bacteria convert nitrogen gas into a usable form (ammonium) that plants can absorb through their roots. This process is called nitrogen fixation and is essential for plant growth and development.
They don't get the nitrogen from the atmosphere. They get it from the soil, compost and mulch are usually nitrogen deficient, and there are two form of nitrogen in the ground ,one the plant can use,and one that need a bacteria to break its bonds so the plant can us
Only in compound form. Some of these absorbable forms compounds of nitrogen are naturally produced by lightning strikes that convert atmospheric nitrogen into ammonia, which dissolves in rain water, but most natural nitrogen in a chemical form that can be absorbed by plants enters the soil from decay of dead animal and plant materials and waste eliminated by animals. in well civilized areas, the latter type of absorbable nitrogen is often supplemented by manufactured or mined materials, especially nitrates and ammonia.
Most plants absorb nitrates and ammonia from decomposing organic matter in the soil.
A few plants absorb ammonia from nodules of symbiotic anaerobic nitrogen fixing bacteria growing inside their roots. These bacteria can absorb nitrogen gas directly from the air.
Plants take in nitrogen from the soil through absorption. The plants will take nitrate and ammonium which is the converted into nitrogen through assimilation.
Also the fixation of nitrogen by some plants, directly from air is possible with the help of the enzyme nitrogenase. This process is known from the last part of XIX-th century.

Describe the path of nitrogen through its biogeochemical cycle?
Nitrogen gas in the soil is used by plants, which are eaten by animals. The waste products of the animals contain the nitrogen. It is broken down by bacteria, which releases nitrogen gas into the atmosphere, and the cycle repeats.
How does nitrogen get in the earths atmosphere?
Nitrogen is present in the Earth's atmosphere primarily as a result of volcanic eruptions and geologic activities releasing nitrogen from rocks. Additionally, nitrogen-fixing bacteria in the soil convert nitrogen from the air into a form that plants can use, which can eventually be released back into the atmosphere through various processes.
If nearly 79 of the atmosphere is made of nitrogen how could there be a shortage of nitrogen in soil?
Although the atmosphere is rich in nitrogen gas, plants cannot use this form directly. Nitrogen needs to be converted into a usable form like nitrates by soil bacteria for plants to uptake. In cases where the soil lacks these nitrogen-fixing bacteria or has been depleted due to overfarming, there can be a shortage of available nitrogen for plants.
Which gas makes up 78 percent of our atmosphere but can be used by plants only when transformed by bacteria first?
Nitrogen gas makes up 78% of our atmosphere, but plants can only use it when it is transformed into a usable form by nitrogen-fixing bacteria, such as Rhizobium or Azotobacter. This conversion process allows plants to absorb the nitrogen in the form of ammonia or nitrates.
What is the transfer of nitrogen from air to soil to organism and back to air and soil?
Nitrogen fixation by certain bacteria in soil converts atmospheric nitrogen into a form usable by plants. Plants take up nitrogen from soil through their roots, incorporating it into their tissues. When plants and animals die, decomposers break down their remains, releasing nitrogen back into the soil. Some nitrogen is also released back into the atmosphere through processes like denitrification.
Do plants take in nitrogen directly from the atmosphere?
Most plants cannot take in nitrogen directly from the atmosphere. Instead, they rely on nitrogen-fixing bacteria in the soil to convert atmospheric nitrogen into a form that plants can absorb, usually in the form of nitrate or ammonium. Leguminous plants, like peas and beans, have a symbiotic relationship with nitrogen-fixing bacteria in their root nodules.
Describe the path of nitrogen from the atmosphere to plant proteins?
Nitrogen gas in the atmosphere is converted by nitrogen-fixing bacteria into a form that plants can absorb, such as ammonium or nitrate. Plants take up these nitrogen compounds from the soil through their roots and incorporate them into proteins. When animals eat plants, they obtain nitrogen from plant proteins, continuing the cycle.
Do animals take in nitrogen directly from the atmosphere?
No, animals do not take in nitrogen directly from the atmosphere. They obtain nitrogen through consuming plants or other animals that have already processed nitrogen into organic compounds. Nitrogen fixation by certain bacteria in the soil or symbiotic organisms in plants helps convert atmospheric nitrogen into forms that can be used by animals.
What is the transfer of nitrogen from the atmosphere to plants and back to the atmosphere or directly into plants again?
The transfer of nitrogen from the atmosphere to plants and back occurs through a process called nitrogen fixation. This can happen through the action of nitrogen-fixing bacteria that convert nitrogen gas into a form that plants can use. Once plants assimilate this nitrogen, it can be returned to the atmosphere through processes like denitrification or can be transferred to other organisms through the food chain.
How do plants and animals get nitrogen is not from the atmosphere?
In rainforests where there is loads of leeching, plants get their nitrogen from other dead plants, where a nitrogen cycle is established
Describe the path of nitrogen through its biogeochemical cycle?

What plants absorb nitrogen from the atmosphere?
Cannabis
Does the nitrogen cycle has no atmospheric component?
No, the nitrogen cycle does have an atmospheric component. Nitrogen gas in the atmosphere is converted by certain bacteria into forms that can be used by plants through a process called nitrogen fixation. Plants then take up these usable forms of nitrogen and incorporate them into their tissues.
What is an example of nitrogen fixing a process essential for life on Earth?
The answer choices are:Plants take in nitrogen gas from the atmosphere.Bacteria convert nitrogen gas into a form that plants can use.Water absorbs nitrogen.Animals take in nitrogen gas from the atmosphere.
What elements are most organisms unable to take from the atmosphere?
nitrogen
When there is not enough nitrogen in the atmosphere for plants how do the plants get it?
Plants can obtain nitrogen from the soil through their roots. They form symbiotic relationships with nitrogen-fixing bacteria in the soil, which convert atmospheric nitrogen into a form that plants can use. Additionally, decaying organic matter in the soil releases nitrogen that plants can absorb.
What is largest source of nitrogen?
Nitrogen is the most abundant element in the Earth's atmosphere. Bacteria in the soil 'fix' the nitrogen gas into compounds which can be taken in by plants; the plants get eaten by animals & they use the nitrogen to make proteins.
