Light energy is absorbed by chlorophyll, a green substance found in chloroplasts in some plant cells and algae. Absorbed light energy is used to convert carbon dioxide and water into a sugar called glucose. Oxygen is released as a by-product.
a plant produces energy for animals and humans first the roots store the nuterans and food the plants need then the steam helps carry the food and energy to the lefts which helps the plant or food grow and give humans and animals energy that they need
