Answer 2

Option B

Plants use carbon dioxide to make food

Step-by-step explanation:

Plants use carbon dioxide to make their food in the presence of sunlight, water and air. This process is called photosynthesis.

The chlorophyll in the leaves of a plant, gives it a special ability to produce food when it is exposed to the ultraviolet radiations from the sun. One of the key components in this its building up process is carbon dioxide.

Without carbon dioxide, it will be difficult for plants to make their food naturally.
