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.
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.
All organisms need nitrogen because it is a component of all proteins and many other essential molecules.

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.
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.
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.
Nitrogen is required by plants and animals for protein synthesis
Biology relies on chemistry. The nitrogen must be able to attach to the receptor molecule to be used. Nitrogen fixation renders nitrogen into a less s table form so that it can break bonds and attach to other molecules.
proteins
Most organisms are unable to make nitrogen directly from the atmosphere. Instead, they rely on nitrogen-fixing bacteria to convert atmospheric nitrogen into a form that can be used by plants and other organisms for essential functions like protein synthesis.
Nitrogen is necessary for life to thrive because it is a key component of proteins, DNA, and other essential molecules in living organisms. Plants and other organisms rely on nitrogen to grow and reproduce, making it crucial for the functioning of ecosystems and the overall health of living organisms.

Living things that need nitrogen to make complex nitrogen compounds are called nitrogen-fixing organisms. These organisms have the ability to convert atmospheric nitrogen gas (N2) into usable forms such as ammonia or nitrates, which can be incorporated into various biological molecules. Examples of nitrogen-fixing organisms include certain bacteria and some plants, such as legumes.

Nitrogen is the critical component of amino acids, which are the building blocks of protein. Since all organisms need protein for their cellular structure, no organism, that we know of, can exist without some nitrogen. There are different modes of acquiring nitrogen, however. The legumes, such as beans, are plants that can "fix" atmospheric nitrogen into amino acids, and thus do not need to acquire it from other organisms, like we do. There are also some bacteria that are capable of fixing nitrogen.
