Question

Why is the sun an important form of energy for all living things?

Answer 1

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.

Answer 2

The sun's energy gives power to everything on Earth. Plants use sunlight to make food. Animals get their energy by eating plants. Even animals that eat other animals get their energy from plants. And all of the energy in plants comes from the sun. Energy from the sun is called solar energy.
