Question
Solar energy trapped by green plants finally returns to the environment. Comment.

Answer

Plants also convert sunlight into other forms of energy. In this case plants convert light energy.
  1. Into chemical energy, (in molecular bonds), through a process known as photosynthesis. Most of this energy is stored in compounds called carbohydrates. The plants convert a tiny amount of the light they receive into food energy. When animals eat green plants
  2. They consume and absorb some of this energy, which stored as chemical energy in compounds known as fats and protein. Milk from cows is a good source of solar energy
  3. (Also an excellent source of essential vitamins and minerals). When we drink milk our bodies convert the energy stored in the milk into energy for running, playing and important metabolic activities
  4. We have become “solar powered”!
