The energy associated with food is chemical energy.
The food contain carbohydrates, proteins, vitamins and minerals, that are used by chemical reactions in the live organisms (the metabolism) to build the cells that form our tissues (muscles, bones, blood).
The chemical energy is stored as chemical bonds in the cells and is released when the bonds break giving energy that we use to run about, and move and talk (kinetic and sound energy).
Answer:
The cave painting on the image is representing the animals, or rather the environment that was seen by the artists of the painting in their surroundings. We can see that there are wild horses depicted on it, but also a rhino. The wild horses were probably a prey animal, while the rhino was a respected animal and feared one, thus they were avoiding it. The artists that painted it were the Cro-Magnons, early Homo-sapiens in Europe, in what is now France. The reason why it was painted is probably because the artist wanted to depict the environment, but also maybe for teaching the youngsters about the animals from early age, so that they know which ones are to be hunted, and which ones to be avoided.
