Answer:
In plants photosynthesis occurs in two steps light-dependent stage and light-independent stage.
ATP is energy carrier and NADPH is electron carrier and both are produced during the first step from the sunlight as they carry the energy and electron to the next step which is light-independent step. In this step both ATP and NADPH are used in the formation of sugars from carbohydrates.
Therefore, these molecules connect the light-dependent and light- independent reactions of photosynthesis.

Explanation:
Selection pressure means factors that contribute to selection which variations will provide the individual with an increase chance of surviving over others. Because of selective pressures, organisms with certain phenotypes have an advantage when it comes to survival and reproduction. Over time, this leads to evolution.
