<h3><u>Answer;</u></h3>
b) cycle both carbon and oxygen
<h3><u>Explanation</u>;</h3>
- Photosynthesis and cellular respiration are complementary processes by which living things obtain needed substances.
- They both consume and create the same substances (water, glucose, oxygen, and carbon dioxide) but in different ways.
- <em><u>Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. </u></em>
- <em><u>While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.</u></em>
