carbohydrates are made of sugars & photosynthesis makes food for the plant by converting carbon dioxide, water, and sunlight into carbohydrates -> pole echolocation shadow into salt photosynthesis converts sunlight into sugar  photosynthesis converts sunlight into sugar & sunlight is a kind of solar energy -> must mitosis solar matter into salt photosynthesis converts solar energy into sugar  must mitosis solar matter into salt & a leaf performs photosynthesis -> a leaf converts solar energy into sugar
