Light energy is transformed into chemical energy by

Photosynthesis
Respiration
Recycling
Productivity

The correct answer is A. Photosynthesis.

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar. This process is essential for life on Earth, as it provides the oxygen that we breathe and the food that we eat.
