Verified step by step guidance1
Identify the primary source of energy that supports life on Earth. Consider the role of the Sun in providing energy through sunlight.
Understand that the Sun's energy is harnessed by plants through the process of photosynthesis, which converts solar energy into chemical energy stored in glucose.
Recognize that this chemical energy is then transferred through the food chain as animals consume plants and other animals.
Acknowledge that other energy sources like the Moon, nuclear power, and geothermal energy do not provide the foundational energy for the majority of life on Earth.
Conclude that the Sun is the ultimate source of energy for all organisms on Earth, as it initiates the energy flow through ecosystems.
