Question
How does the burial of dead plant tissue affect atmospheric CO2 and O2?
The atmospheric reservoir of CO2 shrinks and the atmospheric reservoir of O2 expands.
The atmospheric reservoirs of CO2 and O2 stay the same.
The atmospheric reservoir of CO2 shrinks and the atmospheric reservoir of O2 stays the same.
The atmospheric reservoir of CO2 expands and the atmospheric reservoir of O2 shrinks
a.The atmospheric reservoir of CO2 shrinks and the atmospheric reservoir of O2 expands.
b.The atmospheric reservoirs of CO2 and O2 stay the same.
c.The atmospheric reservoir of CO2 shrinks and the atmospheric reservoir of O2 stays the same.
d.The atmospheric reservoir of CO2 expands and the atmospheric reservoir of O2 shrinks
Explanation / Answer
The atmospheric reservoir of CO2 shrinks and the atmospheric reservoir of O2 expands
The dead plant contains the CO2 which is buried hence the atmospheric CO2 reservior shrinks. The O2 which would have been used to decompose the organic matter of dead plant is saved so the O2 reservior expands.
