Nitrogen-Fixing bacteria. aka Rhizobium
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 cycle. Some nitrifying bacteria lives in the roots of legumes, and do the same job.
Bacteria that convert nitrogen gas into a form plants can use (nitrogen fixation) play a crucial role in the nitrogen cycle, ensuring the availability of nitrogen for plant growth. Bacteria that convert ammonia to nitrate (nitrification) make nitrogen more readily available to plants. These processes are essential for plant growth and ecosystem functioning.
Plants use nitrogen a N- and air has N2. Nitrogen fixation changes nitrogen into a form that plants can use.
Producers, like plants, are important to the nitrogen cycle because they are able to convert atmospheric nitrogen into a form that can be used by living organisms. Through nitrogen fixation, producers play a key role in making nitrogen available for other organisms in the ecosystem.

Plants consume nitrogen in the form of Nitrates. Nitrogen gets converted into nitrates by the denitrifying bacteria. These plants absorb nitrogen in the form of nitrates through the groundwater.
The first step of the nitrogen cycle is nitrogen fixation.

Nitrification, an important step in the nitrogen cycle.
They absorb nitrogen from the air. Then nitrogen-fixing bacteria convert it to a useable form.
The nitrogen cycle involves both physical and chemical changes. Physical changes include nitrogen fixation by bacteria and nitrification, while chemical changes include denitrification and ammonification.
Nitrogen fixation is the process by which certain bacteria convert atmospheric nitrogen into a form that plants can use. This contributes to the nitrogen cycle by making nitrogen available for plant growth, which then gets passed on to animals and eventually returns to the soil through decomposition, completing the cycle.
Bacteria in root nodules convert nitrogen gas into ammonia, which can then be used by plants to synthesize proteins and other essential molecules. This process is known as nitrogen fixation and is important for the nitrogen cycle in ecosystems.
