What is the main source of energy for living things?

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.

What is the best form of energy?

Nuclear Has The Highest Capacity Factor

As you can see, nuclear energy has by far the highest capacity factor of any other energy source. This basically means nuclear power plants are producing maximum power more than 93% of the time during the year.

What are the 7 energy sources?

What food is the main source of energy?
