Where does the energy that powers all life on Earth come from?
1 answer
The energy that powers all life on Earth primarily comes from the Sun. Sunlight contains photons, which are packets of energy. Through the process of photosynthesis, plants capture the energy from sunlight and convert it into chemical energy in the form of glucose, which is used as fuel to power their metabolism. Other organisms, such as animals and fungi, rely on consuming plants or other animals to obtain this energy. Therefore, the ultimate source of energy for all life on Earth can be traced back to the Sun.
