After the caterpillar eats a leaf, it can convert the chemical energy into mechanical energy to help build a cocoon. The leaf as their source of food contains mostly of starch and cellulose. This must be break down into smaller compounds by enzymes. The smaller compounds will enter into the different parts of the caterpillars’ body for nutrition. The nutrients that are received by its body will be used for other body processes such as movement in building a cocoon.

Answer///air resistance,drag;

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
