Answer:

A: Chemical

B: Mechanical

C: Heat

D: Light

E: Electrical

Step-by-step explanation:

A: The energy in food is known as chemical energy. Chemical energy is the energy which is stored in the molecular bonds of the compounds (eg. glucose). Hence, when food is digested, many molecules are broken down to their most basic components.

B: Energy that can be used to "do work" is known as mechanical energy. Mechanical energy is energy (usually kinetic and potential energy) which is used to produce a force to an object, and in this conversion, the object then does work (eg. A body of water being used to push a turbine to create electricity).

C: The kinetic energy in atoms/molecules while vibrating is known as heat. Heat energy can be measured as the temperature of a certain substance, but it is actually the sum of all the kinetic energy of every single molecule/atom

D: The energy given off by the sun which allows us to view our surroundings is known as light energy. Light energy enters our eyes and is converted to an electrical impulse that our brain interprets as colour.

E: When electrons move from atom to atom, this is known as electrical energy. This energy is usually found as a property of metals, where they have a "sea" of localised electrons that can allow for the conduction of electricity
