What element must be fixed by bacteria?
Nitrogen
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.
Nitrogen in the atmosphere must be fixed before it can be used by plants. Atmospheric nitrogen is fixed by?
bacteria and lighntning
Can nitrogen gas be used by plants?
No. Plants cannot use elemental nitrogen. The nitrogen must first be fixed, either by lightning or by nitrogen-fixing bacteria. Some plants have such bacteria in their roots.
How is nitrogen fixed in the soil?
Bacteria that exist in the root nodules of some plants can absorb nitrogen from the air in the soil. One notable example is the Rhizobia that lives in nodules on soybean roots. Similar root systems exist in clover and alfalfa.
What element can be fixed into plant material by bacteria?
I believe the answer is nitrogen. http://chemistry.about.com/od/geochemistry/ss/nitrogencycle.htm
Who or what uses the nitrogen after the bacteria has fixed it?
Bacteria
An element is selective in the frequency of light it will absorb This selectivity is due to its?
Every element can only absorb certain wavelengths of light because of how the electrons are positioned around the nucleus. There is a fixed number of energy levels that each electron may move to, and each move will only occur if a specific amount of energy is absorbed. Thus each element, having differing electron orbital states can only absorb certain frequencies of light.
Why are bacteria required in nitrogen cycle?
Nitrogen needs to be fixed before it is used by plants.
How does bacteria benefit plants?
Nitrogen fixing bacteria are important for plants as they can convert Nitrogen from the air into Nitrates in the soil which the plant can then use. Legumes have nodules on their roots to provide a suitable habitat for them.
