    It is not Gravity, Nuclear or Electrical so it must be Chemical.

    Food is essential to SOME living organisms because of its stored chemical energy.  That chemical energy can be released on demand. It is not true that ALL organisms need this because plants use solar energy to create that food.  They do not need food.  They take simple chemicals and use solar energy to synthesize "food".

    Note that the sugars created by plants are still used during times of darkness so perhaps you might say that food is still a part of what is essential to them.

    You should be able to eliminate the others by the what if concept.

    a) Does food contain electricity?

    b) Do we use nuclear reactions to gain energy from food?

    c) Does food provide gravity?

    You should be able to reject each and every one of these leaving only chemical energy.

    Food is essential to the survival of all organisms because of its stored chemical potential energy (typically expressed in Cal per weight unit)

    The energy stored within the bonds between atoms that make up the macromolecules (protein, lipids, carbohydrates) we consume are a form of chemical energy. The process of digestion breaks down food to its smallest forms by breaking these bonds.

    Even if you don't know the answer, you should be able to eliminate three of the choices out of hand.

    Hint: think "sugar."

    Try googling electrical, nuclear, chemical and gravitational energy.
