All life on planet Earth depends ultimately upon the conversion of light energy from the sun through a process called photosynthesis.
Sunlight.
The ultimate source for living thins is the sun. This is because the sun provides things on the absolute bottom of the food chain with food. They are then used as food for the next living thing on the food chain. Things on the bottom of the food chain are called producers. They perform photosynthesis to convert the suns light into useable energy. Organisms the can create their own food are called autotrophs.
The type of molecule that serves as a living things main source of energy is a carbohydrate. The most important carbohydrate is glucose. Glucose is the basic form of fuel in living things.

Living things or plants
living things need water, air, sunlight, healthy food etc. to carry on their life processes.
The sun
The Sun is the ultimate source of energy for living things. The Sun is approximately 865,000 miles wide, and roughly 74 percent of its mass is made up of hydrogen.
The sun is the ultimate source of energy in living things since plants use sunlight to make glucose and other animals use the glucose by eating the plants.
glucose is the source of energy for all living things.
