Forest vegetation absorbs CO2 from the atmosphere during the photosynthesis and accumulates in plant biomass as solid carbon in the process of growth. A significant portion of this accumulated carbon re-enters the atmosphere through plant respiration, forest fire and decay of biomass (Apps et al. Burning of plant biomass for energy also releases carbon back to the atmosphere. The carbon removed from forests through cutting also comes back to the atmosphere either in short or long term depending on where the forest products are put to use.
