The graph below shows the amount of a certain gas absorbed by plants during photosynthesis. In 2-3 sentences, explain the reason why the graph peaks at the times shown in the graph. Grading Considerations: Your answer must include: 2-3 complete sentences What times the graph peaks Why the graph peaks at these times, using reactants and products of photosynthesis to explain your answer. Your answer should be 2-3 sentences in length. Answers longer than 4 sentences will not be considered. Answering concisely and to the point is evidence of your understanding of the topic.

Answer 1

The graph peaks in the early morning and late afternoon, likely corresponding to optimal light conditions for photosynthesis. During these times, increased sunlight promotes the absorption of carbon dioxide (reactant) by the plants, enhancing photosynthesis and leading to greater production of glucose and oxygen (products). As light intensity decreases, the rate of photosynthesis also declines, causing the graph to fall.
