Last Answer : Biological nitrogen Fixation

Nitrification is the biological process of converting – (1) N9 into nitrate (2) N2 into nitrite (3) Ammonia into nitrite (4) Ammonia into N2

Description : Nitrification is the biological process of converting – (1) N9 into nitrate (2) N2 into nitrite (3) Ammonia into nitrite (4) Ammonia into N2

Last Answer : (3) Ammonia into nitrite Explanation: Nitrification is the biological oxidation of ammonia or ammonium to nitrite followed by the oxidation of the nitrite to nitrate. The transformation of ammonia ... limiting step of nitrification. Nitrification is an important step in the nitrogen cycle in soil.

Nitrification is the biological process of converting (1) N2 into nitrate (2) N2 into nitrite (3) Ammonia into nitrite (4) Ammonia into N2

Description : Nitrification is the biological process of converting (1) N2 into nitrate (2) N2 into nitrite (3) Ammonia into nitrite (4) Ammonia into N2

Last Answer : Ammonia into nitrite
