What kind of plants host bacteria nodules that fix free nitrogen?

Rhizobia bacteria are primarily responsible for pulling nitrogen out of the air and making it available to plants, which then use the nitrogen to create proteins.
The legume family (the pea & bean family) of plants are able to form a mutually beneficial relationship with rhizobia bacteria.

What process involves the capture and conversion of nitrogen into a form usable by plants?
Nitrifying bacteria can convert atmospheric nitrogen in to nitrates that plants can use in the soil. That is why leguminous plants having these micro-organisms in the nodules enrich the soil for nitrogen deficiency.
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.
Where does the free nitrogen produced by bacteria eventually go?
N2 (Nitrogen) went atmosphere eventually. (By bacteria)
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 do nitogen-fixing bacteria do?
Nitrogen fixing bacteria change nitrogen from the air into nitrogen compounds such as ammonia, nitrate, and nitrogen dioxide. They do so, through two living arrangements. One's as free living bacteria in the soil. The other's in association with plants of the Fabaceae and Leguminosae families, such as beans and peas. In this arrangement, the plant gives the bacteria sugars in the form of exudates [waste products]. In return, the bacteria provides the plant with nitrogen in forms that the plant can take in.
What converts nitrogen from a form that can be assimilated by plants to N2.?
it is bacteria and lightening or decomposers, not sure. I am doing the same biology homework crap that Ms. elliot signed to all the students over break. i am looking for the same answer i think decomposers is the answer. its the one that makes most sense. :D

What type of bacteria is found in legumes?
Special class of bacteria called Rhizomes live on the roots of leguminus plants. They take free nitrate and nitrites from the environment and change to a form that can be readily used by plants. Relationship between nitrogen fixing bacteria and plants is called Symbiosis.
How do plants get nitrogen from the atmosphere?
Direct nitrogen fixation is performed by a rather specific kind of organism that probably lived free before the atmosphere began to contain oxygen. Today these are anaerobic bacteria that live in nodules on the roots of plants, particularly the legumes. The actual process is brought about by enzymes called nitrogenases. It is an energy intensive process, requiring a lot of ATP in acid conditions. To fix one molecule of nitrogen requires sixteen ATP molecules and the product is ammonia, which is immediately converted to ammonium ion by acid hydrogen. This is still not available to the plant, but if excreted into the soil other aerobic bacteria convert it to nitrite using oxygen, and then nitrate, and this is available to the plant. Another pathway is to convert the ammonium directly into glutamic acid, which the plant can use directly to generate protein.
What is the purpose of nitrogen-fixing bacteria?
Although the air is made up of about 70% nitrogen, plants cannot use nitrogen in this N2 form. Nitrogen fixing bacteria change nitrogen into the form of soluble nitrates so that plants can use it. Other bacteria, known as de-nitrifying bacteria, change nitrates back into N2, which completes the nitrogen cycle Updated by: Levi Levitt
What is the symbolic relationship found between plants and nitrogen fixing bacteria?
Nitrogen is vital to plants (as well as all other life) as it is a key component of chlorophyll, proteins, and DNA. Without nitrogen fixing bacteria, most plants would quickly deplete the limited stores of nitrogen found in the soil in their immediate area. Nitrogen fixing bacteria are able to synthesize ammonia from free nitrogen in the air, and plants can utilize this ammonia in all of their biological processes.
Why is nitrogenous fertilizer not added in soil in which leguminous plants are grown?
Because leguminous plants are capable of fixing free nitrogen from the air with help of their root nodules. Thus soil get rich in nitrates in those places where these plants are grown.
What type of organism is able to covert free nitrogen from the atmosphere to form that is usable for animals?
Nitrogen fixing bacteria will enable some plants to convert atmospheric oxygen to a form that can be used by plants. The plants are then eaten by animals.
What causes nitrogen Fixation?
nitrogen fixation is caused by the bacteria called rhizobium.
Does plants take in nitrogen directly from air?
NO. Nitrogen is a required nutrient for plants but it is obtained from ammonia or nitrates used as fertilizers. Some plants can "fix" (convert nitrogen in the air to an usable form) with the assistance of microorganisms living at the roots.
What bacteria convert nitrites into nitrates?
Nitrogen fixation occurs in1 free living bacteria and archaea e.g. Azotobacter, Klebsiella, Clostridium, and Methanococcus,2 bacteria living in symbiotic association with plants such as legumes e.g. Rhizobium3 cyanobacteria e.g. Nostoc, Anabaena, and Trichodesmia.
