Plants need bacteria in order to take up and use which element?

A. Carbon
B. Oxygen
C. Nitrogen
D. Hydrogen

The answer is nitrogen. Plants cannot use atmospheric nitrogen directly. Nitrogen from the air must be converted into the different form so plants can absorb it. Thus plants need nitrogen-fixing bacteria to convert atmospheric nitrogen into ammonium, which is available for plants to absorb it.

Plants rely on nitrogen-fixing bacteria to convert atmospheric nitrogen (N₂) into usable forms such as ammonia. These bacteria are essential for plant growth as nitrogen is vital for synthesizing proteins and nucleic acids. Thus, the correct answer is C. Nitrogen.
