Answer;
C) ATP
Explanation;
-Photosynthesis can be divided into two parts: the light-dependent reactions and the light-independent reactions (also referred to as the "dark" reactions).
-The two products of the light-dependent reactions of photosystem are ATP and NADPH. The movement of high energy electrons releases the free energy that is needed to produce these molecules. The ATP and NADPH are used in the light-independent reactions to make sugar.
-The light-independent reactions, or dark reactions, of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma, the fluid-filled area of a chloroplast outside the thylakoid membranes.
Bacteria is good, but there is some bad. in this case, your talking about your digestive track therefore, this is good bacteria and what bacteria does is it breaks down the stuff that your body cannot break down by itself so the answer is C I hope this helped and I hope it was the branist answer
