Most nitrogen is fixed by what?
The fixing of nitrogen is an important part of the nitrogen cycle. Nitrogen fixing bacteria fix the nitrogen back into the atmosphere.
What puts nitrogen in soil?
Nitrogen fixing bacteria that live in root nodules of members of the legume family of plants. Some Nitrogen is also fixed during lightning strikes.
Atmospheric nitrogen is fixed by?
bacteria and lightning
What are the two ways nitrogen can be fixed?
Bacteria and Lighting
What is the path of nitrogen from the atmosphere to plants?
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.
How does nitrogen fixed by nitrogen fixing bacteria?

Where can one find information on nitrogen fixing bacteria?
The Encyclopedia Britannica has a lot of great information on nitrogen fixing bacteria. According to the Encyclopedia Britannica nitrogen fixing bacteria are microorganisms capable of transforming atmospheric nitrogen into fixed nitrogen.
Can nitrogen gas be used by plants?
No. Plants cannot use elemental nitrogen. The nitrogen must first be fixed, either by lightning or by nitrogen-fixing bacteria. Some plants have such bacteria in their roots.

Who or what uses the nitrogen after the bacteria has fixed it?
Bacteria
What is the main way nitrogen gets from the atmosphere to earth?
lightening bolts ionized air molecules and create nitrogen compounds which are then carried by rain water down to the earth. Nitrogen-fixing bacteria would be responsible for the greatest bulk of fixed nitrogen.
What does it mean to have nitrogen fixed?
Nitrogen fixation is the conversion of atmospheric nitrogen, N2, into some biological form, such as ammonia, NH3, or nitrogen dioxide, NO2. In nature, this process is most often completed by nitrogen-fixing bacteria or diazotrophs. Nitrogen fixation is important because only fixed nitrogen can be used for basic biological substances such as proteins and nucleic acids.
What is the need of fixing atmospheric nitrogen find out the various ways by which atmospheric nitrogen is fixed?
Why does atmospheric nitrogen need to be converted?
Atmospheric nitrogen is fixed by?
bacteria and lightning
What element must be fixed by bacteria?
Nitrogen
Nitrogen in the atmosphere must be fixed before it can be used by plants. Atmospheric nitrogen is fixed by?
bacteria and lighntning
