Plants use carbon dioxide to make food.

Explanation:

Photosynthesis may be defined as the phenomena by which plants prepare their food with the help of sunlight. Plants produce oxygen during the process of photosynthesis.

The main component required for the photosynthesis if the carbon dioxide gas. The carbon dioxide gas is obtained by the plants from the atmosphere. They use carbon dioxide to prepare their food.

Thus, the correct answer is option (2).

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

ok yes, but what is the question? as soon as you ask the actual question i will answer it. : )
