KWWSVGRLRUJ316 3XEOLVKHGRQOLQHE\&DPEULGJH8QLYHUVLW\3UHVV in the studies are undertaken, mat Nitrogen cycle. . In . physico. -chemical process, the atmospheric nitrogen combines with oxygen during lightning or electrical discharges in the clouds and produces different nitrogen oxides. These nitrogen oxides get dissolved in rain water, and on reaching earth surface they react with mineral compounds to form nitrates and other nitrogenous compounds. excretion and urea cycle; regulation of urea cycle;. Nitrogen excretion:. Nitrogen excretion means elimination of nitrogen containing compounds from an organism.. Urine is the main rout for such excretion, also take place through feces..
