Answer:
Photosynthesis transforms solar energy (sun) into chemical energy
Step-by-step explanation:
Photosynthesis in plants converts solar energy into chemical energy using electrons and protons from water. The process of photosynthesis in plants involves a series of steps and reactions (light-dependent and light-independent) that use solar energy, water, and carbon dioxide to produce organic compounds and oxygen. Energy from sunlight is absorbed by chlorophyll (the green pigment) and that energy is converted into stored chemical energy.
Also, strange question, considering the energy transformation in autotrophs is photosynthesis.
