Before humans the main path is from Nitrogen fixing bacteria found in the roots of many plants and from lightning creating nitrogen oxides that are then washed down with the rain. In modern times more than half the nitrogen fixed is from the application of artificial fertiisers and from air polution.

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.
How does the nitrogen cycle work in the environment?
The nitrogen cycle is a process in which nitrogen moves between the atmosphere, soil, and living organisms. Nitrogen gas in the atmosphere is converted into a form that plants can use by nitrogen-fixing bacteria in the soil. Plants then take up this nitrogen through their roots. When plants and animals die, decomposers break down their organic matter, releasing nitrogen back into the soil. This cycle continues as nitrogen is recycled and reused by different organisms in the environment.
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.
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.
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 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
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.
What is one path a nitrogen molecule might follow through the ecosystem?
A nitrogen molecule in the atmosphere can be converted into a form that plants can use through nitrogen fixation by bacteria in the soil. Plants take up the nitrogen from the soil and incorporate it into their tissues. When animals eat the plants, they obtain the nitrogen, which eventually returns to the soil through decomposition of plant and animal matter.
What plants absorb nitrogen from the atmosphere?
Cannabis
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.
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.
How do microorganisms make nitrogen in the atmosphere usuable to plants?
By fixing free nitrogen from the atmosphere through endogenous or exogenous methods.
Why plants and animals unable to absorb nitrogen directly for atmosphere?
Nitrogen is not very reactive
Where does nitrogen from the atmosphere go before it enters the plants?
The nitrogen goes into the nodules of the plant.
What natural processes renew supply of nitrogen in the atmosphere?
Nitrogen-fixing bacteria in the soil and roots of certain plants convert nitrogen gas from the atmosphere into a form that plants can use. Lightning also plays a role in converting nitrogen gas into compounds that can be used by plants.
