Restoring the Balance
Restoring the Balance is a Grade 7 science concept from Amplify Science (California) Chapter 4: Science Seminar on Deforestation, explaining how forest conservation stabilizes the global carbon cycle. Protecting forests preserves their capacity for photosynthesis, which removes excess CO2 from the atmosphere and maintains the balance of the global carbon reservoir.
Key Concepts
Maintaining large scale forest ecosystems is essential for regulating the global carbon cycle. It ensures that the mechanism for removing excess carbon dioxide from the atmosphere remains intact.
Common Questions
How does forest conservation restore atmospheric balance?
Forests contain billions of trees that perform photosynthesis, removing CO2 from the atmosphere. Conserving forests preserves this carbon-removal capacity, preventing atmospheric CO2 from rising.
What is the role of forests in the global carbon cycle?
Forests act as a major carbon sink, absorbing CO2 through photosynthesis and storing carbon in biomass. They are essential for regulating atmospheric CO2 levels.
Why does deforestation disrupt the carbon balance?
When forests are cleared, trees can no longer perform photosynthesis to remove CO2, and the stored carbon is released as CO2 through burning or decomposition, increasing atmospheric concentrations.
What do Grade 7 students study in the Amplify Science deforestation case study?
Students analyze how deforestation disrupts the global carbon cycle and evaluate evidence supporting conservation as a strategy to stabilize atmospheric CO2 and the biosphere.
