NITROGEN METABOLISM FIXATION

NITROGEN METABOLISM. Nitrogen Fixation can be defined as the conversion of molecular nitrogen into fixed form of nitrogen to make it available for absorption by plants.It is the third most important process after respiration and photosynthesis.It is essential for all living organisms. . CLASSIFICA
