No. They can not use nitrogen gas because the triple bonds of nitrogen can only be broken down for use in living things, plants, by the symbiotic bacteria in the root nodes. Then in other forms nitrogen is taken up into the plant and from there to other trophic levels.
Most organisms take in nitrogen from the soil in the form of nitrates and ammonia, which are produced by nitrogen-fixing bacteria. These bacteria convert nitrogen gas from the air into usable forms. Some aquatic organisms can also directly uptake nitrogen from water in the form of nitrate, nitrite, or ammonia.
Most of the nitrogen that bacteria use comes from the atmosphere in the form of nitrogen gas (N2). Some bacteria, known as nitrogen-fixing bacteria, have the ability to convert atmospheric nitrogen into a form that can be used by other organisms, such as ammonia or nitrate.
Nitrogen cannot form solid minerals on the Earth.
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.
Free nitrogen refers to the nitrogen gas (N2) present in the atmosphere, which is not readily available for use by most organisms. Fixed nitrogen, however, is nitrogen that has been converted into a form that can be utilized by plants and other organisms, such as ammonia, nitrate, or nitrite. This conversion process is often carried out by nitrogen-fixing bacteria in the soil.
Nitrogen gas (N2) is unusable by most organisms because they lack the ability to convert it into a usable form like ammonia (NH3) or nitrate (NO3-). This process, known as nitrogen fixation, is carried out by certain bacteria and archaea.
Since the air around you is about 78% nitrogen gas, you might think it would be easy for organisms to retrieve nitrogen easily. However, most organisms cannot use nitrogen gas. Nitrogen gas is called "free" nitrogen because it's not combined with other atoms. Most organisms can use nitrogen only when it has been combined with other elements to form nitrogen-containing compounds. So, is that the answer you were looking for (possibly for homework)?
Nitrogen gas in the atmosphere is in a very stable form (N2) and requires a large amount of energy to be converted into a usable form by living organisms. This process, called nitrogen fixation, is carried out mainly by specialized bacteria. It is energetically demanding and cannot be done by most organisms, making the integration of atmospheric nitrogen into the biosphere challenging.
No, most organisms cannot use free nitrogen gas from the air. Instead, certain bacteria have the ability to convert atmospheric nitrogen into a form that plants can absorb and utilize. This process is known as nitrogen fixation.
Most organisms take in nitrogen from the soil in the form of nitrates and ammonia, which are produced by nitrogen-fixing bacteria. These bacteria convert nitrogen gas from the air into usable forms. Some aquatic organisms can also directly uptake nitrogen from water in the form of nitrate, nitrite, or ammonia.
Nitrogen gas cannot be used directly by most organisms because it is a very stable molecule (N2) that is difficult to break apart biologically. Some organisms, such as nitrogen-fixing bacteria, have special enzymes that allow them to convert atmospheric nitrogen into a form that can be used by plants and other organisms.
Nitrogen
Most of the nitrogen that bacteria use comes from the atmosphere in the form of nitrogen gas (N2). Some bacteria, known as nitrogen-fixing bacteria, have the ability to convert atmospheric nitrogen into a form that can be used by other organisms, such as ammonia or nitrate.
Most of the free nitrogen on Earth is found in the atmosphere, where it makes up about 78% of the air we breathe. Nitrogen gas (N2) is abundant in the atmosphere, but it is not readily available for use by most living organisms in this form.
Nitrogen cannot form solid minerals on the Earth.
Organisms known as nitrogen-fixing bacteria, such as certain species of Rhizobium, Azotobacter, and Cyanobacteria, can convert nitrogen gas (N2) into ammonia (NH3) through a process called nitrogen fixation. This ammonia can then be used by plants and other organisms in the form of nitrates for essential functions.
in its most common form; yes.
