Why the sun is the ultimate source of energy for all living organisms?

The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.

Moreover, why is the sun is the main source of energy?

The Sun is the primary source of energy for Earth's climate system is the first of seven Essential Principles of Climate Sciences.
