Heat energy, mechanic energy, and new chemical energy.
Energy.
When food gets digested in our body, energy is released after its breakdown.
It is essentially chemical energy, which is released when the food is digested in the stomach
Energy is released from digested food within the cells
Energy. All food eaten is digested. Food is a chemical that, once digested, turns to energy :) Thats what I Learnt Anyway :)
The food that isn't digested is called waste.
Carbon dioxide and water are produced as byproducts, along with energy in the form of ATP. Oxygen is consumed during cellular respiration to be used in the process of breaking down glucose to produce energy for the cell.

Chemical energy.
Digestion is necessary because for energy from the food to be released and carried into the cells in our body the food must be broken down into soluble molecules for it to diffuse into the cells. Then energy is released during respiration.
In a unicellular organism like Paramecium, food is stored and digested in a structure called a food vacuole. Once the food vacuole is formed, enzymes are released to break down the food particles for absorption and energy production.
