Best Answer

Photosynthesis is the use of sunlight to power the creation of sugars from carbon dioxide and water. Where's cellular respiration is the reaction of sugars and oxygen to create energy. Because the sugar is being broken down by the oxygen, we would consider cellular respiration to be the one that uses oxygen to break down molecules.

What product of photosynthesis is needed by both plants and other organisms for cellular respiration?

The products of photosynthesis are glucose and oxygen. Oxygen is used in cellular respiration.


How do cellular respiration and photosynthesis relate to each other?

The products of photosynthesis are used as the reactants for cellular respiration, and vice versa. Photosynthesis uses carbon dioxide (CO2) and water (H2O) to create organic molecules and oxygen (O2). In turn, cellular respiration takes those two products (oxygen and organic molecules) to create carbon dioxide (CO2) and water (H2O)

How are Photosynthesis and Cell Respiration linked?

Photosynthesis takes the energy from sunlight and uses it to put together large sugar molecules from the raw ingredients CO2 and H2O. Cellular respiration occurs when organisms break down large sugar molecules to use the energy to do work and release the waste products CO2 and H2O


How do you describe carbon and oxygen cycle?

The two processes of the carbon cycle are photosynthesis and cellular respiration. In photosynthesis carbon from carbon dioxide is fixed into carbohydrates. In cellular respiration, carbohydrates are broken down to form ATP and carbon in the form of carbon dioxide is released into the atmosphere.The two processes of the oxygen cycle are also photosynthesis and cellular respiration. In photosynthesis, oxygen is produced by the splitting of water and is released into the atmosphere. Oxygen is used in the process of aerobic cellular respiration as the last electron acceptor in the electron transport chain. The oxygen then combines with hydrogen to form water molecules, which can then be used by photosynthesis and the cycle is complete.
