Directions: Read each scenario and explain how photosynthesis and plant growth will be affected in each one. Explain in complete sentences using evidence to support your position. Scenario 1: If an area experienced a drought that lasted for months, with lakes and rivers dropping to levels lower than anyone could remember, what would be the effect on photosynthesis of plants in the area?
Scenario 2: If there were a series of volcanic eruptions and the volcanic ash accumulated in Earth’s atmosphere, what might be the effect on photosynthesis?
Scenario 3: If an area experienced several weeks during which the temperature rose every day to 37–38°C (98.6–104°F), what would you predict about the rate of photosynthesis in this area?
