Question

Is plants use their nitrogen in fixed form, i.e., incorporated in compounds, such as nitrate ions (no3−), ammonium ions (nh4+), and urea (nh2)2co?

Answer 1

nitrate ions(no3-).......

Answer 2

According to the substances mentioned in the question , plants use nitrogen in fixed form, i.e., incorporated in compounds, such as nitrate ions (no3−), ammonium ions (nh4+), and urea (nh2)2co.

The above mentioned statement is completely true.

Because,the working with non-fixed forms of the nitrogen compounds is far more complicated than the fixed forms, that's why plants prefer dealing with the fixed forms of the nitrogen compounds.
