Assertion : The atmospheric concentration of $C{O}_2$ at which photosynthesis just compensates for respiration is referred to as $C{O}_2$ compensation point.

Reason : The $C{O}_2$ compensation point is reached when the amount of $C{O}_2$ uptake is less than that generated through respiration because the level of $C{O}_2$ in the atmosphere is more than that required for achieving $C{O}_2$ compensation point.
