Question
Explain how deforestation contributes to an increase in carbon dioxide levels in the atmosphere.
Answer
Deforestation increases carbon dioxide levels by reducing the number of trees available for photosynthesis, which absorbs carbon dioxide. Additionally, when trees are burned or decompose, the carbon stored in their biomass is released back into the atmosphere as carbon dioxide.
Explanation
This answer effectively addresses the mechanisms by which deforestation impacts carbon dioxide levels, testing the student's understanding of the relationship between trees, photosynthesis, and carbon emissions.
Common mistake
Deforestation and Carbon Dioxide
Students often state that deforestation only increases carbon dioxide by burning trees, neglecting the role of reduced photosynthesis.
Emphasize that deforestation increases carbon dioxide both by burning trees and by reducing the number of trees available for photosynthesis, which absorbs carbon dioxide.
