Rate this question:
Sunlight breaks down the gases released by burning biomass before they reach the atmosphere.
Gases released by burning biomass contain more environmental pollutants than the gases released by burning fossil fuels.
Plants capture CO2 during photosynthesis and release it when they are burned as biomass.
CO2 released by burning biomass is from a natural source and does not affect the atmosphere.
