Which of these organisms could be chosen for a study of both photosynthesis and cellular respiration? a. a simple plant b. a chemosynthetic bacterium c. an animal that eats plants d. an animal that eats animals

I think that the answer would be a simple plant because im not sure if a chemosynthetic bacterium can undergo photosynthsis andanimals cannot undergo photosynthsis, however as a part of life all plants AND animals use cellular respiration (for plants this happes durring the night when the sun is down)
