My claim is photosynthesis does models the Law of Conservation of Matter and Energy because photosynthesis allows plants to store/reuse matter and energy. My first piece of evidence that supports the law of conservation of energy is when a bird eats a caterpillar then the bird gets the energy from the worm “so the bird indirectly gets the energy that began with glucose.” (Photosynthesis by ck-12 , n.d) My next piece of evidence is the sun's energy (light energy) is used to make the plants food glucose, which is the plant's energy, this shows the Law of Conservation of Matter because the light energy is transformed into something new which is the plant's food . (photosynthesis , n.d) My final piece of evidence is photosynthesis equation
