E.
caused by the movement of electrons

Answer 1

Food energy is stored as chemical bond energy between organic molecules (usually carbohydrates and lipids--on occasion amino acid compounds, I think).

The kinetic energy in moving water is mechanical, as kinetic energy is quite literally by definition a component of mechanical energy (along with potential).

Light is a form of energy visible to the human eye; there are photoreceptors somewhere on our eye that can interpret the wavelength of incident light, and translate this into recognition.

The total kinetic energy of atoms making up a sample of matter is, according to the kinetic theory of temperature, is heat. Well, it's also pressure, but PV=nRT establishes the relationship. As things increase in heat or pressure, what's really happening at a microscopic scale is atoms moving faster.

Electron movement is electrical energy. Charge and all that.
