A sunflower reacts to the energy of photons; energy emanates from thermonuclear reactions in the sun; makes things grow, i.e. do work; is the driving force of evolution, and the means of economic activity in human social affairs; it can be transformed and or stored in many forms, e.g. solar energy, nuclear energy, light, heat, kinetic energy, potential energy, etc.; is the central component in all of science, e.g. chemistry: activation energy, entropy, bond energy, etc., or thermodynamics: internal energy, Gibbs free energy, etc.; it is equivalent to mass: E=mc2 and has its mysteries, e.g. dark energy.
