residual lung volume - amount of air left in the lungs after exhaling


Explain why residual lung volume exists - keep the alveoli open even after
maximum expiration which allows for continual gas exchange to occur between
breaths.


Explain how the circular processes of photosynthesis and cellular respiration result
in the cycling of carbon within ecosystems. - CR produces CO2 and water which
PS uses to make O2 and glucose which CR uses


Explain the two reasons for an imbalance in this cycle that led to the increased O2
during the Carboniferous. - 1. Increase in photosynthesis
2. Burial of carbon- removed from the cycle


Describe the hypothesized reasons for the decline in O2 during the late Permian -
Land masses form super-continent which led to a dryer climate and a reduction in
photosynthesis which led to the reduced burial of carbon and then O2 dropped as
more carbon entered cellular respiration


Explain the importance of Lignin on the rise and fall of O2 levels during the
Carboniferous - Lignin allows coal formation and allows excess O2 to stay in the
atmosphere


Explain the importance of Lignin Decomposition on the rise and fall of O2 levels
during the Carboniferous - Lignin Decop did not allow coal formation and did not
allow excess O2 to stay in the atmosphere which increased PS
