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 diffrence between fixed nitrogen and free nitrogen?
OK well free nitrogen is fixed by bacteria that live in the soil. some bacteria live in nodules, or bumps , on certain plant roots. the bacteria get food from the plants, and plants absorb fixed nitrogen from the bacteria. animals get nitrogen by eating plants or by eating prey that have eaten plants. fixed nitrogen may enter the soil in other ways too. a small amount of free nitrogen in the air by lighting. it is carried to the ground by rainfall. fixed nitrogen also enters the soil because of decomposers. decomposers break down dead organisms, and fixed nitrogen is released in the soil. the fixed nitrogen can be absorbed by plant roots.
When nitrogen is fixed it is changed into?
Yes it is.
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 does 'fixed' mean in biogeochemistry?
nonvolatile,as a vegetable oil, incorporated into a stable compound from its free state, as atmospheric nitrogen, OR permanently held, as a fabric dye
What are the bacterias in the nitrogen cycle?
Nitrogen needs to be fixed before it is used by plants.
