What is the overall outcome of the light reactions in photosynthesis? 22 . Why are carnivores, such as lions, dependent on photosynthesis to survive? 23 . Why are energy carriers thought of as either “full” or “empty”? 24 . Describe how the grey wolf population would be impacted by a volcanic eruption that spewed a dense ash cloud that blocked sunlight in a section of Yellowstone National Park. 25 . How does the closing of the stomata limit photosynthesis? 26 . Describe the pathway of electron transfer from photosystem II to photosystem I in light-dependent reactions. 27 . What are the roles of ATP and NADPH in photosynthesis? 29 . Why is the third stage of the Calvin cycle called the regeneration stage? 32 . Imagine a sealed terrarium containing a plant and a beetle. How does each organism provide resources for the other? Could each organism survive if it was the only living thing in the terrarium? Why or why not?

Part B Photosynthesis plays an important role in maintaining life in most ecosystems on Earth because it has an impact on how organisms obtain their energy. In your science journal, write a claim that supports the idea that photosynthesis helps sustain life on Earth, and support that claim with at least one piece of evidence. Use the rubric below to assist you with your response. Criteria Scale Makes Claim about Photosynthesis and Supports Claim with Evidence 2 This response includes both a claim about photosynthesis and its importance, and supports the claim with one piece of factual evidence. 1 This response either lacks both a claim and a piece of evidence, or contains a faulty claim or irrelevant/faulty evidence. 0 This response lacks the required components for partial credit.
