What are 2 differences and similarities between these two processes?

The two processes are similar in that they both produce energy, albeit in two different forms. They are different in that photosynthesis assembles the glucose molecule, while cellular respiration takes it apart.Photosynthesis produces the oxygen to replenish oxygen that is used up by living organisms during respiration. Carbon dioxide produced during respiration is one of the reactants plants need to perform photosynthesis. Photosynthesis and cellular respiration are both part of a mutually beneficial relationship.Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide.

Explanation:

The principal difference, however, between photosynthesis and respiration is that photosynthesis utilizes carbon dioxide and water in the presence of light to produce glucose and oxygen, whereas respiration uses oxygen and glucose to power the activities of the cell.Both processes need carbon dioxide to produce the carbohydrates. Both processes also need an energy source to fuel the reactions. And, most important, both photosynthesis and chemosynthesis result in food for the organisms, which in turn becomes food for other organisms, supporting the circle of life.Photosynthesis and respiration are reactions that complement each other in the environment. They are in reality the same reactions but occurring in reverse. While in photosynthesis carbon dioxide and water yield glucose and oxygen, through the respiration process glucose and oxygen yield carbon dioxide and water.

thermophiles, notice the prefix thermo.

there’s no image attached but i can if you want: )
