You are a marine biologist sampling an offshore ecosystem. One day, you find a red organism floating in one of your nets. It has structures that resemble the leaves and stems of a plant. You hypothesize that this organism might be photosynthetic. Describe how you could test this hypothesis using a pH indicator solution.
a. In detail, describe the steps you would take and the reactants of photosynthesis required.
b. What change in pH would indicate that the organism was undergoing photosynthesis, and how would the indicator respond?

energy.
C. Living organisms breakdown sugar from food to combine with oxygen making usable
energy.
D. Living organisms take in oxygen and release carbon dioxide through the cells thereby
providing energy.
