Vedclass · Answer

(B) Plants require nitrogen for the synthesis of proteins and other compounds. Although nitrogen is abundant in the atmosphere,plants cannot absorb it directly in its gaseous form $(N_2)$.Most plants absorb nitrogen from the soil in the form of inorganic compounds,primarily as nitrates $(NO_3^-)$ and nitrites $(NO_2^-)$.Some plants can also absorb nitrogen in the form of urea or ammonium ions,but nitrates and nitrites are the most common forms absorbed by the majority of plants.Therefore,the correct forms are $(ii)$ Nitrates and Nitrites and $(iii)$ Urea.

$(i)$ Proteins
$(ii)$ Nitrates and Nitrites
$(iii)$ Urea
$(iv)$ Atmospheric nitrogen
