Assertion : The atmospheric concentration of CO2 at which photosynthesis just compensates for respiration is referred to as CO2 compensation point.
Reason : The CO2 compensation point is reached when the amount of CO2 uptake is less than that generated through respiration because the level of CO2 in the atmosphere is more than that required for achieving CO2 compensation point.
Both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.
Both Assertion and Reason are true but the Reason is not the correct explanation of the Assertion.
Assertion is true statement but Reason is false.
Both Assertion Reason are false statements.
