Question

1.Absorption of nitrogen by the plants happens along with _________ in the soil.2.___________ converts gaseous nitrogen into usable form for plants.

Answer 1

Nitrosomonas bacteria first convert nitrogen gas to nitrite (NO2-) and subsequently nitrobacter convert nitrite to nitrate (NO3-), a plant nutrient. Plants absorb ammonium and nitrate during the assimilation process, after which they areconverted into nitrogen-containing organic molecules, such as amino acids and DNA.
