Solar energy is used by plants to make food for themselves and other organisms as well. Plants lie on the bottom of the energy pyramid or first on the food chain. This is because they are producers and other organisms gain energy from them. Solar energy plays a very vital role here, because the process of photosynthesis, which takes place in plants, is incomplete without solar energy. Therefore, we can say it is an ecosystem service.
