Full Description
This exam evaluates the relationship between elevated atmospheric CO2 levels and their effects on plant photosynthetic rates. Students will analyze mechanisms by which plants respond to changes in carbon dioxide concentration.
With rising atmospheric CO2 due to climate change, understanding plant responses is vital for predicting ecosystem dynamics and agricultural productivity. This knowledge is critical for developing effective mitigation strategies in land management.
Candidates will demonstrate an understanding of how increased CO2 levels influence photosynthesis, carbon allocation, and biomass production in various plant species.
Additionally, students may be asked to evaluate contrasting responses of C3 and C4 plants to elevated CO2 and discuss implications for food security.
Sample Questions
- What mechanisms do plants utilize to adapt to elevated atmospheric CO2 levels?
- How do C3 and C4 plants differ in their responses to increased carbon dioxide concentration?
