Nitrogen gas composes 70% of the atmosphere but because it is so stable it remains a gas and unusable to plant. Bacteria have evolved that can break the N2 bond and provide nitrogen as a soluble product to the roots of plants. Once taken up by the plant the nitrogen moves through the food chain to animals etc.

What is a peocess by which bacteria remove nitrogen from the air and make it avaliable to plants-?
Nitrogen fixation is the process by which bacteria remove nitrogen from the air and make it available to plants.
What does nitrogen fixation mean science?
Nitrogen fixation is the process by which nitrogen gas from the air is combined with some other element, such as hydrogen to make ammonia, or to make any other compound containing nitrogen.
Why is nitrogen fixation important to living things?
Plants need nitrogen in order to grow. Nitrogen is abundant in the earth's atmosphere, but plants cannot use it in that particular form (nitrogen gas). Certain bacteria which reside on some plant roots are able to change atmospheric nitrogen into a form that plants can use (ammonia).
What is the process of combining nitrogen with oxygen or hydrogen to make it usable to organisms?
The process of combining nitrogen with oxygen or hydrogen to make it usable to organisms is known as nitrogen fixation. This occurs naturally through lightning strikes or by certain bacteria in the soil and roots of legumes, which convert atmospheric nitrogen (N₂) into ammonia (NH₃) or related compounds. These forms of nitrogen can then be taken up by plants and used to synthesize amino acids and nucleotides, which are essential for life. Additionally, industrial processes, like the Haber-Bosch method, also synthesize ammonia for fertilizers, further facilitating nitrogen's availability to organisms.
What is the process by which bacteria remove nitrogen from the air and make it available for plants?
Bacteria performs nitrogen fixation, which involves converting the atmospheric nitrogen (N2) into usable organic nitrates (NO3-). Said bacteria are often referred to as nitrogen fixating bacteria. The process is sometimes called nitrification.Scientists have been able to give plants genes from bacteria to help them do a beeter job. This process is called recombinant DNA technology. Nitrogen fixing bacteria are in root nodules on legumes and maybe some other plant groups.Converts nitrogen in the air to nitrates.

Nitrogen fixation is the process by which bacteria remove nitrogen from the air and make it available to plants.
What is the process by which gaseous nitrogen is converted into ammonia a compound that organisms can use to make amino acids and other nitrogen-containig organic molecules?
Nitrogen fixation
What is fixation in the nitrogen cycle and how does it contribute to the overall process of nitrogen cycling in the environment?
Fixation in the nitrogen cycle is the process by which certain bacteria convert atmospheric nitrogen gas into a form that plants can use, such as ammonia or nitrate. This is important because plants need nitrogen to grow, and fixation helps make nitrogen available in the soil. Overall, fixation is a crucial step in the nitrogen cycle as it helps maintain a balance of nitrogen in the environment, supporting plant growth and ecosystem health.
What happens during the process of nitrogen fixation and how does it contribute to the overall nitrogen cycle"?
During nitrogen fixation, certain bacteria convert atmospheric nitrogen into a form that plants can use, like ammonia. This process helps make nitrogen available for plant growth, which then enters the food chain as animals consume plants. Overall, nitrogen fixation is essential for maintaining the balance of nitrogen in ecosystems and supporting plant growth.
What does nitrogen fixation mean science?
Nitrogen fixation is the process by which nitrogen gas from the air is combined with some other element, such as hydrogen to make ammonia, or to make any other compound containing nitrogen.
Which process describes nitrogen fixation?
Bacteria combines with hydrogen to make ammonia, which is changed and turned into compounds such as nitrate or nitrogeNitrogen fixation is the natural process, either biological or abiotic, by which nitrogen (N2) in the atmosphere is converted into ammonia (NH3).
What converts gaseous nitrogen into ammonia in the nitrogen cycle?
Nitrogen-fixing bacteria, such as Rhizobium and Azotobacter, convert gaseous nitrogen into ammonia through a process called nitrogen fixation. This process helps make nitrogen available to plants for growth and is a key step in the nitrogen cycle.
Describe why nitrogen must cycle through an ecosystem?
Nitrogen must be cycled through an ecosystem so that the nitrogen is available for organisms to make proteins.
How is nitrogen fixation carried out?
Nitrogen fixation is the process by which nitrogen is taken from its relatively inert molecular form (N2) in the atmosphere and converted into nitrogen compounds useful for other chemical processes (such as, notably, ammonia, nitrate and nitrogen dioxide).
Why is nitrogen fixation important to living things?
Plants need nitrogen in order to grow. Nitrogen is abundant in the earth's atmosphere, but plants cannot use it in that particular form (nitrogen gas). Certain bacteria which reside on some plant roots are able to change atmospheric nitrogen into a form that plants can use (ammonia).
Why must nitrogen cycle through an ecosystem?
Nitrogen is essential for the growth and survival of living organisms, as it is a key component of proteins and DNA. The nitrogen cycle facilitates the conversion of nitrogen between different forms that can be utilized by organisms in the ecosystem. This cycling process ensures that nitrogen is continuously available for plants and other organisms to support their growth and metabolism.
What is the process of combining nitrogen with oxygen or hydrogen to make it usable to organisms?
The process of combining nitrogen with oxygen or hydrogen to make it usable to organisms is known as nitrogen fixation. This occurs naturally through lightning strikes or by certain bacteria in the soil and roots of legumes, which convert atmospheric nitrogen (N₂) into ammonia (NH₃) or related compounds.
