By which free nitrogen (N2) is extracted from the atmosphere and converted (fixed) into nitrogen compounds which are plant nutrients (fertilizer).

Gram stain technique is a method use to classify bacteria into large groups base on their different cell wall components. It differentiate gram positive and gram negative by coloring them with red or Violet colors.
Gram stain is use for identification and classification of bacteria.
Gram positive stain violet due to presence of thick layers of peptidoglylcan in their cell walls and gram negative stain red due to thin layers of peptidoglylcan in their cell walls.
