It’s a common question: why can’t humans survive on sunlight alone? The answer lies in the fact that plants have a unique advantage – chloroplasts containing chlorophyll. These structures allow plants to capture energy from sunlight and convert it into usable energy. Unfortunately, humans lack both chlorophyll and chloroplasts, making it impossible for us to survive solely on sunlight. While we may be able to absorb some vitamin D from the sun, we still require a balanced diet of nutrients to sustain ourselves.
