Question

Carbon dioxide added by biomass burning is

• A. 80%
• B. 60%
• C. 40%
• D. 25%

Answer 1

Answer: (C)

40%

The burning of the biomass releases the stored energy in the form of heat and carbon dioxide. It has contributed around 40% of the carbon dioxide to the atmosphere, so it is also a cause of the greenhouse effect. Biomass such as wood, solid organic waste, fossil fuels etc. are extensively used as the source of energy. Their heightened usage is responsible for anthropogenic contribution to the carbon dioxide accumulation in the atmosphere and global warming as a result of it.

Hence, the correct answer is '40%'.
