Using evidence, explain how photosynthesis and cellular respiration are interconnected in the carbon cycle.

• Photosynthesis releases carbon dioxide, which is used in cellular respiration.

• Photosynthesis and cellular respiration are unrelated processes.

• Photosynthesis uses carbon dioxide, which is released during cellular respiration.

• Cellular respiration produces glucose, which is used in photosynthesis.

Strategically plan an experiment to demonstrate the conservation of mass during photosynthesis.

• Measure the mass of a plant before and after photosynthesis without considering inputs and outputs.

• Measure the mass of carbon dioxide and water before photosynthesis and compare it to the mass of glucose and oxygen produced.

• Only measure the mass of oxygen produced.

• Only measure the mass of glucose produced.
