9189 Biomass Quiz

What is biomass?

• A type of fossil fuel

• A biological material that can be burnt to produce heat

• A synthetic material used in construction

• A type of renewable energy source that does not release carbon dioxide

Why does burning biomass not add to global warming?

• It does not release carbon dioxide

• It releases carbon dioxide that was recently absorbed

• It absorbs carbon dioxide during combustion

• It is a non-renewable resource

What is the main difference between biomass and fossil fuels in terms of carbon dioxide?

• Biomass does not release carbon dioxide when burnt

• Fossil fuels absorb carbon dioxide during combustion

• Biomass releases carbon dioxide that was recently absorbed, while fossil fuels release carbon dioxide stored for millions of years

• Fossil fuels do not contribute to global warming

What process allows plants and trees to absorb carbon?

• Combustion

• Photosynthesis

• Respiration

• Decomposition
