Using your knowledge of photosynthesis and cell respiration, draw a picture of the hydrogen cycle and the oxygen cycle. (Hint: Consult the 4 cycles in the book for guidance.)
What will be an ideal response?
Carbon dioxide (contains oxygen) and water (contains hydrogen and water) are taken up by plants. Using sunlight, glucose and oxygen are the products. The hydrogen from the water has been incorporated into glucose. The oxygen then is taken up by animals and plants for the burning of glucose during respiration, and carbon dioxide and water are released. See Figure 3-16.
