What is the ultimate source of energy in the food we eat?plzz

Answer 1

The ultimate source of energy in the food we eat is the Sun. Through the process of photosynthesis, plants convert sunlight into chemical energy, storing it in the form of carbohydrates. When we consume plant-based foods (or animals that have eaten plants), we obtain this stored energy. Essentially, the energy that fuels the food chain originates from solar energy harnessed by plants and then transferred through various trophic levels as organisms consume one another.
