When did compensation point occurs?

The compensation point occurs when the rate of photosynthesis in plants equals the rate of respiration, resulting in no net gain or loss of biomass. This typically happens under low light conditions or when a plant has just enough light to sustain its metabolic processes. At this point, the energy produced through photosynthesis is used entirely for respiration, meaning the plant is neither growing nor shrinking. The compensation point varies among different plant species and environmental conditions.
