Best Answer

Your answer is invalid, because the plants return the nitrogen back in to the air. I think what you're trying to ask is what forms of nitrogen is taken by the plants. The answer is nitrides, and nitrates. Nitrides are formed by decomposers in the soil and further nitrogen fixation causes nitrides into nitrates. You can notice this through their equation: nitrides (n3) nitrates (no3).

How does nitrogen returned to the atmosphere?

When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use. Other types of bacteria are able to change nitrogen dissolved in waterways into a form that allows it to return to the atmosphere.


Why do plants need nitrogen?

All plants need nitrogen to make amino acids, proteins and DNA, but the nitrogen in the atmosphere is not in a form that they can use. Other plants get the nitrogen they need from the soils or water in which they live mostly in the form of inorganic nitrate (NO3-). Bacteria living in plant nodules in the soil on the roots of the plant also provide the plant with the nitrogen it needs while providing the bacteria a sugar source. Nitrogen is a limiting factor for plant growth.


What is the name of the process when nitrogen is returned to it's gas form?

The process in which nitrogen returns to it's gas form is known as nitrogen fixation


The effects of lighting to nitrogen in the atmosphere?

Lightning helps in the production of a form of nitrogen. Lightning causes oxygen and nitrogen in the atmosphere to chemically react to combine and form nitrogen oxide, a key ingredient in many fertilizers.


How nitrogen can make up almost 80 percent of the atmosphere and still limit plant growth?

The reason nitrogen is abundant in the atmosphere yet limits plant growth is that plants cannot make use of elemental nitrogen. The bond between the nitrogen atoms in elemental nitrogen (which is a diatomic gas) is very strong and not easily broken. Therefore, plants must rely on bacteria in order to fix the nitrogen (convert it into a usable form).


Why do people put nitrogen in plant fertilizer?

People put nitrogen in fertilizers because nitrogen in the form of ammonium nitrogen is essential for a plant's growth.


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.


If nitrogen in the atmosphere is not in a form plants can use how do they get nitrogen what is this process called?

they get threw their roots and it is called nitrogen fixation


If nitrogen in the atmosphere is not a form plants can use how do they get nitrogen what is this process called?

they get threw their roots and it is called nitrogen fixation


What is the elemental form of nitrogen?

In the atmosphere nitrogen takes the form of the diatomic nitrogen molecule, N2.


How do you balance nitrogen monoxide reacts with atmosphere to form nitrogen dioxide?

Youd need to be more specific about the equation, specifically around the atmosphere.


Do burning fuels add nitrogen to the atmosphere?

Yes, burning fossil fuel adds nitrogen, in the form of nitric oxide, to the atmosphere.
