What are the three types of bacteria involved in nitrogen cycle?
The three types of bacteria which are involved in the nitrogen cycle are nitrogen- fixing bacteria which change the nitrogen gas into ammonia. The next is nitrifying bacteria which changes the ammonia into nitrities and then the nitriites into nitrates. Then the plant absorbs the nitrates and uses them to continue growth. Then an animal may eat the plant receiving the nitrogen from it. But it must eventually get ride of it so it produces waste which goes back into the soil and is broken down by decomposers and fungi, which then turn it back into ammonia. The cycle then repeats itself. Extra nitrates are turned back into nitrogen gas by denitrifying bacteria.
How do nitrogen fixing bacteria on root nodules function in 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 cycle. Some nitrifying bacteria lives in the roots of legumes, and do the same job.
Why is it important for nitrogen to be recycled in an ecosystem?
It is important for nitrogen to be recycled in an ecosystem because nitrogen is an essential nutrient for plants and other organisms, necessary for building proteins and DNA. Recycling nitrogen through processes like nitrogen fixation, decomposition, and denitrification ensures that it remains available for use by different organisms, supporting the overall health and productivity of the ecosystem.
What is the role of nitrifying bacteria in making nitrates available to plants?
Nitrifying bacteria convert ammonia (NH3) to nitrites (NO2-) and then to nitrates (NO3-), making nitrogen available in a form that plants can absorb and utilize for growth. This process is known as nitrification and is essential for the nitrogen cycle in soil, providing plants with a vital nutrient for their development.
Process where certain bacteria change nitrogen gas into nitrates in the soil?
The process is called nitrogen fixation. Certain bacteria, like Rhizobium and Azotobacter, convert atmospheric nitrogen gas (N2) into ammonia (NH3) or nitrate (NO3-) that can be used by plants for growth. This conversion is essential in the nitrogen cycle as it makes nitrogen available for plant uptake.
Why are nitrogen fixing bacteria important?
Although the air is made up of about 80% 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
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.
Why are bacteria important to the nitrogen cycle?
because when bacteria convert ammonia into nitrates and nitrites, producers need them to make proteins, and then consumers eat the producers and reuse the nitrogen to make their own proteins.
Where are nitrogen fixing bacteria found and how do these bacteria benefit plants?
Legumes have nitrifying bacteria in their roots, but mostly it is found in the soil. Although the air is made up of about 78% 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
What is the purpose of nitrogen-fixing bacteria?
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.

Where bacteria in the soil change nitrogen gas into forms that plant us?
These bacteria are called nitrogen-fixing bacteria, such as Rhizobium or Azotobacter, which convert atmospheric nitrogen gas into forms usable by plants, like ammonium or nitrates. This process is essential for plant growth as nitrogen is a crucial nutrient for their development.

What role do bacteria play during 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.
What bacteria in the soil can change nitrogen compounds into?
Some bacteria in the soil, like Rhizobium and Azotobacter, are capable of converting nitrogen gas into a form that plants can use, such as ammonium or nitrates. This process is known as nitrogen fixation and is crucial for plant growth and soil fertility.
