6.2B Terrestrial Primary Producers & Sequestration of Carbon

• Terrestrial Sequestration

  • Terrestrial sequestration has the shortest time scale of seconds, minutes or years

  
• • Decomposition is fastest in tropical climates with high temperatures, rainfall and oxygen levels 
  • It is much slower in cold, dry conditions where there is a lack of oxygen
• • The most productive biomes are tropical rainforests, savannah and grasslands where storage is mainly in vegetation
  • Carbon fluxes (flows) within biomes vary with time
  • Diurnally - most active during the day
  • Seasonally most active during the spring and summer months
