Question

What is the original source of energy in the food you eat?

Answer 1

The original source of energy in the food we eat is the sun. Through the process of photosynthesis, plants convert sunlight into chemical energy, producing glucose and other organic compounds. These plants serve as the primary producers in the food chain. When animals eat plants (herbivores) or other animals (carnivores), the energy stored in the plants and other organisms is transferred and utilized. Therefore, ultimately, the energy in our food originates from solar energy captured by plants.
