Statement 2: Air contains mostly nitrogen as its component.

• B. The Both statements are correct and Statement 1 correctly explains Statement 2.
• C. Only Statement 2 is correct.
• D. Both statements are wrong.

Answer 1

The correct option is C

Only Statement 2 is correct.

Even though nitrogen makes up most of the air around us, plants cannot use nitrogen in this form. Nitrogen has to be absorbed in the form of absorbable forms like nitrates or nitrites from the soil. Microorganisms present in the soil converts the atmospheric nitrogen to nitrates and nitrites.
