Higher organisms use nitrogen to make proteins, nucleic acids (DNA and RNA), and other essential molecules necessary for growth and function. Nitrogen is a crucial component of amino acids, which are the building blocks of proteins, and is required for various biological processes within the body.
Organisms can use nitrogen in the forms of ammonium (NH4+), nitrate (NO3-), nitrite (NO2-), and atmospheric nitrogen gas (N2) through nitrogen fixation processes. These forms are essential for building proteins, DNA, and other cellular components in living organisms.
No, nitrogen gas cannot be directly used by most living organisms. Instead, nitrogen-fixing bacteria in the soil or in plant roots convert atmospheric nitrogen into a form (ammonia or nitrates) that can be used by plants to make proteins. Other organisms then obtain nitrogen by consuming these plants.
No, most organisms cannot use the free nitrogen in the air. Instead, certain bacteria and archaea have the ability to convert atmospheric nitrogen into a form that plants can use through a process called nitrogen fixation. This fixed nitrogen then moves through the food chain as organisms consume plants and other organisms.
Nitrogen-fixing bacteria, such as Rhizobium and Azotobacter, are capable of converting gaseous nitrogen in the air into a form that other living organisms can use, such as ammonia or nitrate. These bacteria form symbiotic relationships with plants, providing them with usable nitrogen in exchange for carbohydrates.

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.

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.
Yes, nitrogen-fixing bacteria can convert atmospheric nitrogen (N2) into forms of nitrogen (such as ammonia or nitrates) that are accessible to living organisms. By carrying out nitrogen fixation, these bacteria play a crucial role in making nitrogen available for plants and other organisms to use for essential biological processes.
nitrogen
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)?
