Which process occurs when plants convert light energy into chemical energy?

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

Answer: (B)

The process that occurs when plants convert light energy into chemical energy is known as photosynthesis. During photosynthesis, plants use sunlight, usually absorbed by chlorophyll in the leaves, to convert carbon dioxide taken from the air and water absorbed through the roots into glucose and oxygen. This transformation of light energy into chemical energy stored in glucose is fundamental to the energy cycle within ecosystems, as it provides the primary source of energy for nearly all living organisms. The oxygen produced as a byproduct is also critical for the survival of most life forms on Earth. Photosynthesis not only supports plant growth but also contributes to the global carbon cycle and maintains atmospheric oxygen levels.
