The source of energy for most organisms is chemical energy and sunlight.
The sun
water and electricity
The sun and the sunlight are the main things for all living things.
Sugar
water and electricity
Carbohydrates.
The most common carbohydrate energy source for most organisms is glucose. Other common sugars are fructose and galactose, but glucose by far is the most common. Glucose is not only the most common as a simple sugar (monosaccharide), but also as the basic link in larger polysaccharides, including the disaccharide sucrose and the polymers glycogen and amylose.
autotrophPhotoautotrophs carry out photosynthesis. Light is the energy source and carbon dioxide is the carbon source
They are the lipids. Lipids can store much energy
the sun is the main source of energy for plants since it helps the most with the process of photosynthesis photosynthesis is the process of a plant making it's food which means it does not rely on other organisms for food

The primary energy source for most living systems is nutrients. Nutrients are elements and compounds that organisms consume and require for survival. Organisms need several dozen naturally occurring chemical elements to survive; among these are nitrogen, carbon, and phosphorus.
