No.
See that big ball of light in the sky?
When sunlight hits your skin, Vitamin D is produced.
I dont know if you are considering vitamins a food molecule or not, but liquids also contain energy. As do cardboard, glue, and everything else you mice and rats eat.
Cockroaches can live for years off of the paper and cellulose glue used on you wallboard. (drywall)

Why food coloring dissolves faster in hot water than cold water?
Food colouring dissolves faster in hot water because the water molecules have more energy and they move around more creating larger gaps for the food colouring molecules to fit into, while the cold water has less energy and the water molecules are closser together making it harder for the food colouring to dissolve
Can electrical energy be transformed into chemical energy?
no because electrical energy only flows to electrons while chemical energy consists food.
In terms of kinetic energy explain how a molecule in a liquid evaporates?
Water is made up of many molecules that are in constant, random motion. These molecules collide with each other to gain or lose kinetic energy from or to other molecules. The molecules nearer to the surface of the water and have high enough kinetic energy will be able to change from liquid to gaseous state. Since the molecules with higher kinetic energy have moved out of the water, the average kinetic energy of the water drops which inturns means that the temperature of water will drop as well.
Why can hydrogen be considered a fuel source of the future?
Only if Fusion becomes a reality. Since "free" hydrogen is not available it must be "made" (separated from water, etc.). Thus it can "transport" energy, but it can't be a fuel (or energy) source.
Is chemical energy a type of energy?
of course its a engry because it has the word engry in it Not only because of that but also because an example for a chemical energy is food.
What is food energy needed for?
Food is necessary for survival because the food contains glucose, and glucose is the only source of energy for living organisms.
Is sunlight the only source of energy for the preparation of food by plants?
Plants don't prepare food.
When you digest food is it a new substance?
No, digestion only breaks food down into simpler molecules, such as starches into sugars. The total amount of the basic elements remains unchanged with most of it being passed through as an ineffective source of energy.
What parts of the earth provide us with energy?
None. There is only a transfer of energy. You obtain the energy from a consumed source example: you eat food which causes a transfer of energy but the food does not provide energy.
Is a carbohydrates polymer function?
Carbohydrates or polysaccharides are the primary source of energy for our body.Our brain only uses glucose as its energy source.Carbohydrates are easy to breakdown and if that is not available in diet body tries to get energy from fat molecules.
Role of energy in the body?
Food provides our energy source - energy is needed to extract the oxygen from the atmosphere and diffuse it into our bloodstream. As warm blooded animals we can only digest food and function if our bodies are at 37C - energy is required for this. We need energy to move our muscles which also only operate when they are warm
Give 4 reasons why you need food?
I can only think of 1 reason why you need food:-Food is broken down into molecules which cells use to create a chemical reaction which provides energy to your body. Without energy, you would die.
What is meant by the amount of energy that can be derived from food?
When you eat your body will split the molecules of the food into smaller molecules. When this reaction releases energy. This energy is used to form ATP molecules. ATP molecules are used in the human body to preform actions and because of this it generally refers to energy. Different types of food will result in different amounts of ATP molecules. Because it's made of different substances, one will always be more efficient then the other. This way differs the amount of energy that can be derived from food. I hope this answers your question. Please correct me if I made a mistake. But please be gentle when correcting my spelling and grammar, English ain't my native language :).
Is a bulb a source of energy?
It is a source of light only.
Does boil water gain or lose energy?
You have to put energy IN to keep it boiling, so the water molecules gain energy (from the heating source): the answer is 'GAIN energy' and NOT (as wrongly stated before) 'LOSE' it.water only looses energy when it turns into a solid.and adds energy when turning into a gas
Why is it important that living organisms use food as a source of energy?
because food is the only way to intake energy.Sleeping just rests your body it won't give you energy. Unless you know photosynthisis.....that would be cool
Does a plant only require the correct chemicals to make plant food?
No. A plant also uses sunlight, an external source of energy.
