The result of the light-dependent phase of photosynthesis is the generation of which two energy-rich molecules?

The light-dependent reaction is one of the two reactions of photosynthesis (other is light-independent) which occurs in the thylakoid membranes of organelles called chloroplasts.

The first one uses the energy of light to make molecules needed for the next stage of photosynthesis. Two molecules produced are the energy storage molecule ATP and the reduced electron carrier NADPH. 

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.
