IN EITHER CONDENSATION OR PRECIPITATION
Answer:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration.
Explanation:
The products of Photosynthesis are the reactants of Cellular Respiration and vice-versa. It is also shown in the equation;
Photosynthesis:
= 
Carbon Dioxide + Water + energy from light = Glucose + Oxygen
Cellular Respiration: 
Glucose + Oxygen = Carbon Dioxide + Water + ATP

Commensalism: only one species benefits while the other is neither helped nor harmed. ... Almost positive that its Parasitism tho
