How do plants get their energy from the sun? Explain.
The process of photosynthesis. The sun gives off light and the light is absorbed by the chlorophyll in the plant. Water is collected from the roots and comes together with the light from the sun. The light seperates the water molecules into H2 and 02. CO2 is also absorbed into the plant. The H2 and CO2 come together to make sugar for the plant.
