What is meant by fixed in nitrogen fixation?

Answer 1

Nitrogen Fixation is a process of combining atmospheric nitrogen with other elements to form useful compounds. Nitrogen is essential to living things, but most organisms cannot use nitrogen that is not combined with other elements. This is why nitrogen fixation is important to the continuation of life on earth.

Answer 2

Breakdown of atmospheric nitrogen into simple forms of nitrogen compounds that plants can assimilate by the bacterias like Rhizobium present in the root nodules of the plants is known as nitrogen fixation.

Answer 3

Nitrogen is a critical limiting element for plant growth and production. It is a major component of chlorophyll, the most important pigment needed for photosynthesis, as well as amino acids, the key building blocks of proteins. It is also found in other important biomolecules, such as ATP and nucleic acids. Even though it is one of the most abundant elements (predominately in the form of nitrogen gas (N2) in the Earth's atmosphere), plants can only utilize reduced forms of this element. Plants acquire these forms of "combined" nitrogen by: 1) the addition of ammonia and/or nitrate fertilizer (from the Haber-Bosch process) or manure to soil, 2) the release of these compounds during organic matter decomposition, 3) the conversion of atmospheric nitrogen into the compounds by natural processes, such as lightning, and 4) biological nitrogen fixation

Answer 4

Fixed nitrogen is nitrogen in it's final state

Answer 5

convert it to ammonia or other nitrogen compounds ( like nitrogen dioxide). it's essentially making nitrogen usable and sticking it on organic molecules
