Question

How do plants consume nitrogen?

• A. They directly consume from the atmosphere.
• B. They absorb dissolved nitrogen in water.
• C. The bacteria living in the roots of the plants convert nitrogen to a consumable form.
• D. The bacteria living in the leaves of the plants convert nitrogen to a consumable form.

Answer 1

The correct option is C The bacteria living in the roots of the plants convert nitrogen to a consumable form.

Plants cannot take nitrogen gas directly from the atmosphere. So we have tiny bacteria that live in the soil and roots of some plants. They convert the nitrogen in the air into a different form that plants can use.
