What are the uses of light energy?

*Well the first use of light is photosynthesis which helps organisms such as plants make their food it contracts with energy and glucose to form their food.

*the second use of light is warm if you have a lot of light it can heat so much somewhere and make it feel very warm.

*the third use of light is to be able to see if you didn't have light then whats the point in being able to see you would just have to walk around not knowing where you are or what you are doing.
