Photosynthesis requires light energy.
To determine which kind of energy is required for photosynthesis, we can recall the process of photosynthesis and its requirements. Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose (a type of sugar) and oxygen.
The key requirement for photosynthesis is light energy. Chlorophyll, a pigment found in the chloroplasts of plant cells, absorbs light energy from the sun and initiates the process of photosynthesis. This light energy powers the chemical reactions necessary for plants to convert carbon dioxide and water into glucose and oxygen.
Therefore, the correct response is "light energy."
