The name given to the process of using the absorbed food for producing energy is assimilation.

 The process of using the absorbed food for producing energy is assimilation.

The quantity of light on the light curve at which photosynthesis and respiration rates are precisely equal is known as the compensation point. At this moment, CO2 absorption by photosynthetic routes is perfectly matched to CO2 released by respiration, and O2 uptake by respiration is perfectly matched to oxygen released by photosynthetic pathways.Early mornings and late evenings are the best times to reach this point.
