Answer:
Step-by-step explanation:
Photosynthesis
During photosynthesis light energy from the sun causes carbon dioxide and water to be transformed into glucose (sugar) and oxygen.
Cellular Respiration
Respiration requires glucose and oxygen to make carbon dioxide and water. In the process, chemical energy in the form of adenosine triphosphate (ATP) is released.
How are they related?
ATP is the form of chemical energy all cells require to perform the functions necessary to life.
Photosynthesis releases oxygen into the atmosphere and absorbs carbon dioxide. Respiration requires oxygen to allow cells to make ATP.
