When rate of photosynthesis is equal to the rate of respiration

Vedclass · Answer

(B) The compensation point is the light intensity at which the rate of photosynthesis exactly equals the rate of respiration. At this point,the amount of $CO_2$ produced during respiration is exactly equal to the amount of $CO_2$ consumed during photosynthesis. Consequently,there is no net exchange of $CO_2$ or $O_2$ with the atmosphere. This typically occurs during the early morning and late evening hours when light intensity is low.
