Nitrogen fixing is a process whereby certain bacteria convert basic nitrogen to nitrogen compounds that can be absorbed by a plant's root system, for use by the plant.
You can compare this to human metabolism; the human body needs iron, but we cannot eat nails or iron bars to accomplish this. We must first convert the iron to compounds that our body can assimilate, digest and absorb.

Is it true most nitrogen fixation is performed by plants?
No it is not true. Plants cannot fix nitrogen. Bacteria do the job
What is the relationship between bacteria and plants?
Plants need nitrogen to grow. They are surrounded by nitrogen in the air, but it is not in a form the plants can use. Nitrogen fixing bacteria on the roots of the plant convert (fix) the airborne nitrogen to a form the plants can use to grow.
Why are nitrogen-fixing bacteria important to plants?
nitrogen fixing bacteria fix or attach atmospheric nitrogen in soil or make it easily avialable to the plants as plants need nitrogen as one of their macronutrient element for their growth.
Plants transfer nitrogen in the nitrogen cycle?
Because leguminous plants are those plants which have nitrogen fixing bacteria in their roots in the modules of nitrogen. thus to fix the nitrogen to the soil or in crops is the work of those bacteria namely rhizobium and azotobacter thus without these plants we wont have these bacterias and alos the nitrogen
Plants need bacteria in order to take up and use which element?
Nitrogen. Bacteria can convert or "fix" insoluable Nitrites into soluable Nitrates, which plants can absorb
Which organism fix nitrogen in the soil?
bacteria rhizobium fixes atmospheric nitrogen into air which plants can breathe.

What kind of organism converts nitrogen into a usable form of plants?
Bacteria
What is an important use of rhizobium bacteria?
it is used to fix nitrogen in the the soil for the plants
What role do bacteria play the nitrogen cycle?
Although the air is made up of about 70% nitrogen, plants cannot use nitrogen in this N2 form. Nitrogen fixing bacteria change nitrogen into the form of soluble nitrates so that plants can use it. Other bacteria, known as de-nitrifying bacteria, change nitrates back into N2, which completes the nitrogen cycleThey fix nitrogen into forms usable by plants.

How do plants and microbes interact in mutually beneficial ways?
Some Bacteria fix nitrogen from the air and give it to plants, others degrade complex organic compound into inorganic elements which are taken by the plants; in return plants synthesize organic compounds used by bacteria for energy. Bacteria associated with plants to fix nitrogen and benefited by the plants for space and energy are called symbiotic bacteria.
What two functions of bacteria in the nitrogen cycle?
Bacteria function in the nitrogen cycle as nitrogen fixers and denitrifiers. Nitrogen fixing bacteria take in atrmospheric nitrogen gas and "fix" it into a nitrate or nitrite that can be used by plants. Denitrifiers decompose dead plant tissues and release nitrogen to the atmosphere.
What kind of plants host bacteria nodules that fix free nitrogen?
Rhizobia bacteria are primarily responsible for pulling nitrogen out of the air and making it available to plants, which then use the nitrogen to create proteins. The legume family (the pea & bean family) of plants are able to form a mutually beneficial relationship with rhizobia bacteria.
