Nitrogen fixation primarily involves certain bacteria and archaea that can convert atmospheric nitrogen (N₂) into ammonia (NH₃), a form usable by plants. Key organisms include free-living bacteria like Azotobacter and cyanobacteria, as well as symbiotic bacteria such as Rhizobium, which form nodules on the roots of leguminous plants. Some archaea, particularly in extreme environments, also contribute to this process. Overall, these organisms play a crucial role in the nitrogen cycle, enhancing soil fertility and supporting plant growth.

What organisms return nitrogen back into the air?
The organisms that are involved in the movement of nitrogen between the air and soil and back to the air are plants and bacteria. When plants decompose they release nitrogen and bacteria fixes nitrogen back into the air.
What are the roles of nitrogen in organisms?
Nitrogen is essential for the synthesis of proteins and nucleic acids, which are the building blocks of all living organisms. It is also a component of amino acids, which are necessary for growth and repair of tissues. In addition, nitrogen is involved in various metabolic processes, such as energy production and nitrogen cycle regulation.
Why is free nitrogen a problem for organisms?
Free nitrogen is a problem for organisms because most organisms cannot directly use nitrogen gas (N2) in the atmosphere. Instead, they require nitrogen in a usable form like nitrate or ammonium to build essential molecules like proteins and nucleic acids. Some specialized organisms, like nitrogen-fixing bacteria, can convert free nitrogen into a usable form through a process called nitrogen fixation.
Which macromolecule provides the most nitrogen for organisms?
Proteins provide the most nitrogen for organisms. Proteins are composed of amino acids, and nitrogen is a key component of amino acids. During protein metabolism, nitrogen is utilized by organisms for various biological processes, including growth and repair.
What do organisms rely on to get the nitrogen they need?
Organisms rely on various sources to obtain the nitrogen they need, primarily through the nitrogen cycle. Plants absorb nitrogen from the soil in the form of nitrates and ammonium, which are produced by the decomposition of organic matter and the activity of nitrogen-fixing bacteria. Animals, in turn, acquire nitrogen by consuming plants or other animals. Additionally, some bacteria can convert atmospheric nitrogen into forms usable by living organisms through a process called nitrogen fixation.
Which organisms are most critical in the nitrogen cycle?
Bacteria are most critical in the nitrogen cycle, specifically nitrifying bacteria that convert ammonia to nitrites and then nitrates, and denitrifying bacteria that convert nitrates back to nitrogen gas. These organisms play a crucial role in recycling nitrogen in the environment.
How does atmospheric nitrogen fixation affect organisms?
Atmospheric nitrogen fixation is the process where nitrogen is converted into ammonia. Without nitrogen, organisms couldn't grow, and organisms need nitrogen more than anything to grow.
What organisms return nitrogen back into the air?
The organisms that are involved in the movement of nitrogen between the air and soil and back to the air are plants and bacteria. When plants decompose they release nitrogen and bacteria fixes nitrogen back into the air.
Which organisms captures atmospheric nitrogen for the process of nitrogen fixation?
Legumes. They are the primary plant in an ecosystem, and help convert atmospheric nitrogen in nitrogen in the soil that plants can absorb through their root systems. The process is called nitrogen fixation.The organisms involved in nitrogen fixation are nitrifying bacteria like Azatobacter and Pseudomonas forming root nodules in legumenous plants.
What is organisms that can be transform unusable nitrogen in the atmosphere into chemical compounds containing nitrogen that can be used by other organisms?
Nitrogen-fixing bacteria
What are two types are organisms in the nitrogen fixation?
The two main types of organisms involved in nitrogen fixation are free-living bacteria (such as Azotobacter and Clostridium) that live in the soil and symbiotic bacteria (such as Rhizobium) that form mutualistic relationships with certain plants like legumes. Both types of bacteria convert atmospheric nitrogen into a form that plants can use for growth.
Why are nitrogen oxygen and carbon dioxide important to marine organisms?
Nitrogen is important for marine organisms because it is a key component of amino acids and proteins. Oxygen is vital for respiration in marine organisms, enabling them to extract energy from food. Carbon dioxide is involved in photosynthesis, where marine organisms like phytoplankton use it to produce energy and oxygen.
What does the word faxation mean?
There is no such word. - You may mean 'vexation', which is the act of annoying, irritating, or vexing.
What do urea enzymes and ammonia all have in common?
Urea enzymes and ammonia are both involved in the nitrogen metabolism of organisms. Urea enzymes help in urea synthesis or breakdown, while ammonia is a byproduct of nitrogen metabolism that needs to be efficiently processed or excreted from the body to prevent toxicity. Both play crucial roles in maintaining nitrogen balance in living organisms.
What is the transfer of nitrogen from air to soil to organism?
Nitrogen gas in the air is converted into usable forms by soil bacteria through a process called nitrogen fixation. Plants then take up these forms of nitrogen from the soil. When organisms consume plants, they obtain nitrogen from the plants, and the nitrogen cycles through the food chain as organisms are consumed by other organisms.
What are the roles of nitrogen in organisms?
Nitrogen is essential for the synthesis of proteins and nucleic acids, which are the building blocks of all living organisms. It is also a component of amino acids, which are necessary for growth and repair of tissues. In addition, nitrogen is involved in various metabolic processes, such as energy production and nitrogen cycle regulation.
Why is nitrogen transformation essential for living organisms?
nitrogen has no effect to life
