What is the process by which producers use sunlight to make food?

• A. Photosynthesis
• B. Respiration
• C. Transpiration
• D. Fermentation

Answer: (A)

Producers use sunlight to make food through photosynthesis. In plant cells, chlorophyll in the chloroplasts captures light energy and uses it to drive reactions that combine water and carbon dioxide to form glucose, a sugar that stores energy for growth and daily activities. Oxygen is released as a byproduct of this process. This is how plants turn light into chemical energy they can use. The other processes don’t create food from sunlight: respiration releases energy from stored sugars, transpiration is the loss of water vapor from leaves, and fermentation makes energy without oxygen.
