OK well free nitrogen is fixed by bacteria that live in the soil. some bacteria live in nodules, or bumps , on certain plant roots. the bacteria get food from the plants, and plants absorb fixed nitrogen from the bacteria. animals get nitrogen by eating plants or by eating prey that have eaten plants.

fixed nitrogen may enter the soil in other ways too. a small amount of free nitrogen in the air by lighting. it is carried to the ground by rainfall. fixed nitrogen also enters the soil because of decomposers. decomposers break down dead organisms, and fixed nitrogen is released in the soil. the fixed nitrogen can be absorbed by plant roots.

What is the difference between free nitrogen and fixed nitrogen?

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.


What is the difference between fixed nitrogen and free nitrogen?

Fixed nitrogen refers to nitrogen that has been converted into a form that can be readily used by plants, such as ammonia or nitrates. Free nitrogen, on the other hand, refers to nitrogen gas (N2) that makes up about 78% of the Earth's atmosphere and is not readily available for use by most organisms until it is fixed.


What is the difference between free nitrogen and fixed nitrogen and why is this important?

All life forms need nitrogen to grow. Animals can get it from eating plants. But plants must get it from the soil. Fixed nitrogen (in the forms of nitrate ions - NO3-) is the only type of nitrogen that can be found in the soil.Note that nitrogen (as a gas - N2) makes up most of the air. Most plants can not use it because the molecules are triple-bonded.


What is the process of changing free nitrogen into a usable form of nitrogen?

It is called nitrogen fixing.


What is free nitrogen?

Nitrogen fixation. "nitrogen fixing bacteria" converts free nitrogen from the atmosphere to ammonia. In the presence of Lightening nitrogen and oxygen react together to combine to form nitric oxide (NO), then reacts with water to form nitric acid (HNO3), which is brought to earth by rain. When nitric acid reaches the soil, it ionizes and becomes available to the plants as nitrate.

What is the differences from free nitrogen to fixed nitrogen?

Free nitrogen means chemically free, it has not combined with any other elements. Fixed nitrogen has combined to make ammonium compounds or nitrate compounds which can be easily absorbed by plants and used to make amino acids in the plant cells.

What does 'fixed' mean in biogeochemistry?

nonvolatile,as a vegetable oil, incorporated into a stable compound from its free state, as atmospheric nitrogen, OR permanently held, as a fabric dye


Nitrogen in the atmosphere must be fixed before it can be used by plants. Atmospheric nitrogen is fixed by?

Nitrogen fixation is the process by which certain bacteria convert atmospheric nitrogen into a usable form for plants, such as ammonium or nitrate. This can occur through the activity of symbiotic relationships with leguminous plants, free-living soil bacteria, or industrial processes.


What are the ways in which nitrogen gets fixed in nature?

Nitrogen fixation in nature occurs through biological processes by symbiotic bacteria in plant roots, free-living soil bacteria, and certain types of blue-green algae in water bodies. Additionally, nitrogen can also be fixed through non-biological processes like lightning and industrial processes.


Can most organisms use the free nitrogen in air?

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.
