Intuitively the answer is a chemical reaction. This is true to an extent as outlined below.
Food is essentially organic (carbon based) compounds. So they have carbon, and usually hydrogen components, (others as well but for a general case we can just consider the hydrogen and carbon.) Through chewing and enzymes in the stomach and saliva to food is broken down into a sloppy mess of molecules which can be absorbed into the stomach lining. Up till now no energy has been produced, enzymes work as essentially catalysts, providing sites for reactions. Once the molecules are absorbed they travel via the blood to cells which contain mitochondria these are organelles (you can think of an organelle as an organ of a cell). The mitochondria absorb the molecule and together with oxygen from the lungs and react producing carbon dioxide and water. The products have a lower 'free energy' than the reactants. This means the products are more stable than the reactants, and energy is released in the reaction. (see Gibb's free energy in thermodynamics for more on this). This is aerobic respiration, in anaerobic respiration the organic molecules react with another molecule, (not oxygen) for example sulphur.

Explain how energy is transferred through a food chain?
Energy is transferred through a food chain when an organism eats another organism. As the food chain progresses, less energy is available when an organism is consumed.
The energy from food is not all absorbed by water using the experiment. Why?
some energy is spent heating the apparatus or is transferred to the surroundings (ie, heats the environment). There may have been a draft.
What is an example of a chemical change that food goes through while eating it?
release or gain energy by an object
What Energy-rich food compound that stores chemical energy?
food chain
Is energy from food chemical energy?
yes it chemical energy
What is transeferred from producers to consumers and decomposers through food chains?
Energy is transferred in a food chain. It starts with plants absorbing energy from the sun. It is then transferred up through the food chain by animals that eat plants which are, in turn, eaten by carnivore's.

What is transferred from plants to animals through the food chain?
Energy
How is energy transferred through a food chain?
10% or the energy of THE SUN is transferred. 1 tertiary consumers 10 secondary consumers 100 primary consumers 1000 producers 10000 sun
What shows the loss of energy as it is transferred through the food chain?
Ask anonymous
Why is only some energy transferred in a food chain?
energy is lost through heat excretion and movement
This is a path for the transfer of matter and energy through an ecosystem by eating and being eaten?
Food Chain
How is energy is transferred through trophic levels?
Trophic levels are the positions of organisms in a food chain. Energy is transferred through the trophic levels through ingestion at each level.
What is transferred from organism to organism in a food chain?
energy is transferred from on animal to the other animal. Because energy can't be destroyed only transferred
Is a path for the transfer of matter and energy through an ecosystem by eating and being eaten.?
Biochemical cycles are the main means of energy transfer through an ecosystem. The transfer of energy by eating and being eaten is called the food chain.
What type of energy is Food before it is eaten?
what type of energy is Food before it is eaten
How is energey tranferred through a food chainn?
Lets start with the sun. The sun's energy gets absorbed by the plant. Then the animal such as a rabbit eats the plant. The energy from the plant goes to the rabbit when the rabbit eats it. Then the rabbit gets eaten by a deer or another animal. The energy content being transferred gets lower and lower the farther it transfers through the food chain. Then afterwords lets say that a human would consume a deer. The energy from the deer would be transferred to us, humans.
