    not possible; plants derive their energy from metabolism of soil nutrients.
     accomplished by formation of a hydrogen bond, joining oxygen and hydrogen together to form water.
     moderately efficient; about half of the light energy is converted to chemical energy.
     one of the most efficient processes of nature, often approaching a 100% level of energy conversion.
