The leaves of plants can be thought of as "eating" sunlight. From an energetic perspective this makes sense because:

a. light energy, like chemical energy released when the bonds of food molecules are broken, is a type of kinetic energy.
b. the carbon-oxygen bonds within a photon of light release energy when broken by the enzymes in the chloroplasts.
c. both light energy and food energy can be converted to kinetic energy without the loss of heat.
d. photons are linked together by hydrogen bonds, which release energy when striking the surface of a leaf.
e. the carbon-hydrogen bonds within a photon of light release energy when broken by the enzymes in the chloroplasts.


Ans: a. light energy, like chemical energy released when the bonds of food molecules are broken, is a type of kinetic energy.
