It's called the Law of Conservation of Energy.
That is known as the "Law of Conservation of Energy"; it is also known as the "First Law of Thermodynamics".
energy cannot be create or destroyed
Energy cannot be made or destroyed, but gravity is possible because slows down universal expansion.
Energy cannot be created (aka made) or destroyed, it can only change form.
Energy cannot be "produced", energy cannot be made or destroyed, though we can harvest energy from the wind, sun, fossil fuels and even from splitting an atom
made
None, energy cannot be made or destroyed. It can only change form. The energy you would get from any organic matter is already in the matter. The energy is not being "made". It is just changing form. All matter is just energy.
Because 90% of the energy is consumed by each organism in every trophic level. However, energy IS transformed such as radiant to chemical.
Energy cannot be 'made' or 'destroyed'. It can simply be transformed to a different type of energy. Coal contains chemical energy, which will for example, be converted to heat energy in say a coal fired industrial boiler.
Energy cannot be made or destroyed. It's just their since the Big Bang. If you're asking about how the sun "lights up", it does by transferring helium to hydrogen.
Energy cannot be made or destroyed only changed from one energy to another. e.g in a car when you are moving you are producing kinetic energy but when you apply the brakes to slow down you are changing the kinetic energy to heat energy through the brakes.
The law of conservation of energy states that "energy can not be created (made) or destroyed (made gone)"
It made it less efficient and stated that it was more difficult to convert the thermal energy.
