The Biosphere

View mindmap
  • Biosphere
    • The biosphere includes plants, animals and any other living organisms.
    • All living and deceased organisms contain organic carbon
    • Organisms gain carbon by either extracting it from CO2 in the atmosphere through photosynthesis, or by consuming other organisms and therefore receiving their carbon
    • Carbon remains in an organism until it decomposes sufficiently to release carbon to the atmosphere or lithosphere.
    • It is a closed system
    • Carbon enters the biosphere by respiration and is released by decomposition
