How is biomass an indirect form of solar energy?

Biomass is considered an indirect form of solar energy because it originates from the photosynthesis process, where plants convert sunlight into chemical energy. Through this process, plants absorb sunlight and utilize carbon dioxide and water to produce glucose and oxygen. When biomass is burned or converted into biofuels, the stored solar energy is released, making it a renewable source of energy. Thus, biomass serves as a way to harness solar energy that has been captured and stored by living organisms.
