provide energy to the cells
The Ten Percent Law refers to the transfer of energy from one trophic level to another.
You use chemical energy in almost every part of your daily life. Your body is the perfect example. The food you eat has chemical energy stored in the bonds of the compounds that make it up and digestion breaks those bonds down, releasing that energy. Another example might be driving your car to work; the chemical reaction of burning fuel releases the energy stored in the bonds of gasoline compounds. Anytime you are changing the chemical makeup of something, you have the potential to use chemical energy stored in the chemical bonds.
A system that is 35 percent efficient converts 35 percent of the input energy into useful work or output, while the remaining 65 percent is lost, often as waste heat or through other inefficiencies. For instance, in an engine, if it burns fuel to produce power, a 35 percent efficiency means that only 35 percent of the fuel's energy is effectively used for propulsion, with the rest wasted. This efficiency rating helps gauge performance and indicates potential areas for improvement.

Carbohydrates..they provide energy
Carbohydrates
In the US, 19 percent of electricity. World-wide about 16 percent
The main compounds that serve as the cell fuel supply and provide energy for living things are carbohydrates, such as glucose. These compounds are broken down through cellular respiration to produce ATP, which is used as the main source of energy for various cellular processes.
Carbo-hydrates (sugars).
Structural compounds like cellulose, chitin, and collagen are organic compounds found in living things that are not energy-rich. These compounds provide support and structure for cells and tissues but do not serve as a primary energy source through metabolism.
Lipids are the class of organic compounds that store energy as fat in living organisms. They consist of molecules such as fats, oils, and waxes that are insoluble in water and contain long hydrocarbon chains. Stored fats can be broken down to provide energy when needed by cells.
The light reactions of photosynthesis produce energy-rich compounds like ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). These molecules carry and provide energy for the subsequent dark reactions of photosynthesis.
Fossil fuels are naturally occurring compounds that undergo combustion, releasing energy in the form of heat and light when burned. This energy is harnessed and used for various purposes, such as heating, electricity generation, and transportation.
Gasoline is a mixture of hydrocarbons. As gas is burned, the compounds are broken down into simplier compounds and the breaking of these compounds releases energy.
The energy stored in compounds and released in reactions is chemical energy. It is released when chemical bonds are broken during a reaction, resulting in the formation of new compounds.
