In light-dependent reactions, solar energy is used to make ATP and NADPH. This is used to fuel the light-independent reactions. In the light independent reactions, ADP and an inorganic phosphate P is produced, along with NADP+, which fuels the light dependent reaction.
The independent variable is the type of food available.<span>The dependent variable is the frequency of each type of beak (or number of birds with each beak type)</span>
