What element can be fixed into plant material by bacteria?
Nitrogen is an element that can be fixed into plant material by bacteria. Certain bacteria, like rhizobia and cyanobacteria, have the ability to convert atmospheric nitrogen into a form that plants can use, which helps in the fertilization and growth of plants.
What is the diffrence between fixed nitrogen and free nitrogen?
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 do Most plants use nitrogen in the form of?
Most plants use nitrogen in the form of nitrates (NO3-) and ammonium (NH4+). These forms are readily absorbed by plant roots from the soil. Nitrogen is a crucial component of amino acids, proteins, and nucleic acids, playing a vital role in plant growth and development. Additionally, some plants can also utilize nitrogen fixed by symbiotic bacteria in their root nodules.
What role does bacteria play in nitrigen fixation?
Bacteria play a crucial role in nitrogen fixation by converting atmospheric nitrogen into a form that plants can use, such as ammonia. This process helps enrich the soil with essential nutrients, supporting plant growth and ecosystem health. Some bacteria, like rhizobia and cyanobacteria, have a symbiotic relationship with certain plants and are particularly important for nitrogen fixation.
What 2 things an increase the amount of nitrogen in the nitrogen cycle?
Two factors that can increase the amount of nitrogen in the nitrogen cycle are the use of nitrogen-based fertilizers and the process of nitrogen fixation. Nitrogen-based fertilizers, when applied to crops, enhance soil nitrogen levels, promoting plant growth. Additionally, nitrogen-fixing bacteria in the soil or in the root nodules of legumes convert atmospheric nitrogen into a form that plants can use, naturally enriching the nitrogen content in the ecosystem.
Most nitrogen is fixed by what?
Most nitrogen is fixed by microorganisms in the soil, such as nitrogen-fixing bacteria like Rhizobium and Azotobacter. These bacteria convert atmospheric nitrogen into a form that plants can use, helping to make nitrogen available for plant growth.

How nitrogen can make up almost 80 percent of the atmosphere and still limit plant growth?
The reason nitrogen is abundant in the atmosphere yet limits plant growth is that plants cannot make use of elemental nitrogen. The bond between the nitrogen atoms in elemental nitrogen (which is a diatomic gas) is very strong and not easily broken. Therefore, plants must rely on bacteria in order to fix the nitrogen (convert it into a usable form).
What converts nitrogen into air plants can use?
Nitrogen-fixing bacteria convert nitrogen gas from the air into a form that plants can use, called ammonia. These bacteria form symbiotic relationships with certain plants, such as legumes, providing them with a source of nitrogen for growth and development.
What process effectively makes nitrogen unavailable for plant use?
The reduction of nitrate to gaseous nitrogen. Most plants cannot use atmospheric(gaseous) nitrogen. It must be "fixed" by bacteria in the ground. Plants use nitrogen in the forms of ammonia(NH4+) and nitrate ions(NO3-). source: http://ohioline.osu.edu/aex-fact/0463.html

What percentage of nitrogen is fixed by nitrogen fixing bacteria?
Around 70-80% of nitrogen in the atmosphere is fixed by nitrogen fixing bacteria through a process called nitrogen fixation. This converted nitrogen is then made available for use by plants and other organisms in the environment.
Why must nitrogen be fixed in the nitrogen cycles?
It has to be fixed by things in the soil called nodules, so it can be a form that plants can use in order to get protein to perform photosynthesis.
