Question

what are the importance of nitrogen fixation ? (Give at least three points)

Answer 1

ANS: THE IMPORTANCE OF NITROGEN FIXATION ARE AS FOLLOWS:

1)The reason this process is so important is that animals and plants cannot use atmospheric nitrogen directly.

2)The N2  gas is very abundant (78% of the atmosphere) but it must be converted into another form before most organisms can use it. Bacteria convert it into ammonium (  NH+), which then plants can absorb. Animals get their nitrogen by eating plants or other animals.

3)Finally, all organisms need a steady supply of nitrogen because it is a building block of DNA and RNA, and of proteins. These are vital macromolecules that organisms need to build their genetic info (DNA and RNA) and to carry out many of the processes of life (proteins).
