Which term is used to describe the removal of carbon dioxide from nature by carbon sinks (natural or artificial)?
ADecomposition
BBiosequestration ✓ Correct
CEmission trading
DNone of the above
Correct answer: (B) Biosequestration
Explanation
Biosequestration is the removal of carbon dioxide from the atmosphere by natural or artificial carbon sinks.
Decomposition breaks down dead matter and actually releases carbon dioxide rather than capturing it.
Emission trading is a market mechanism for buying and selling pollution allowances, not a physical carbon removal.
With a precise term available, denying any answer is unwarranted.
Forests, oceans and soils are the main natural carbon sinks that biosequester carbon.
Afforestation and restoring wetlands boost this natural capture.
