Ammonia. I just read that straight from the science book.
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.
The large reservoir of nitrogen that is unusable by most organisms is atmospheric nitrogen (N2). This form of nitrogen is inert and cannot be directly utilized by plants and animals. It needs to be converted into a usable form through the process of nitrogen fixation before it can be incorporated into biological molecules.
Organisms can use nitrogen in the form of nitrate, nitrite, and ammonium. Plants typically absorb nitrate and ammonium from the soil, while some bacteria can convert atmospheric nitrogen gas into a usable form called ammonium.
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.
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.
When dead organisms decay, decomposer organisms break down their tissues and release nitrogen in the form of ammonium. This ammonium is further converted into nitrates by nitrifying bacteria in the soil. These nitrates can then be taken up by plants as nutrients, completing the nitrogen cycle.

Decaying organisms, dead organisms, and waste products form organic matter that provides nutrients for other living organisms. This process is essential for nutrient recycling and sustaining ecosystem health. Over time, the decomposition of these materials helps enrich the soil and support plant growth.
bacteria
When living organisms die, decomposers break down their organic matter. During decomposition, nitrogen is released in the form of ammonia through the process of ammonification. This ammonia can then be converted into nitrites and nitrates through nitrification, which can eventually be denitrified back into nitrogen gas and released back into the atmosphere.

The large reservoir of nitrogen that is unusable by most organisms is atmospheric nitrogen (N2). This form of nitrogen is inert and cannot be directly utilized by plants and animals. It needs to be converted into a usable form through the process of nitrogen fixation before it can be incorporated into biological molecules.
Most organisms obtain nitrogen in the form of nitrate (NO3-) or ammonium (NH4+). These forms of nitrogen are usually present in the soil and can be taken up by plants. Animals then obtain nitrogen by consuming plants or other animals.
Organisms can use nitrogen in the form of nitrate, nitrite, and ammonium. Plants typically absorb nitrate and ammonium from the soil, while some bacteria can convert atmospheric nitrogen gas into a usable form called ammonium.
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.
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.
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.
