Answer:
b. The energy is lost as heat.
This can be explained by analyzing the two chemical equations
The equation for photosynthesis is:
6CO2+6H20--->C6H12O6+6O2
The equation for aerobic respiration is:
C6H12O6+6O2--->6CO2+6H2O
The oxygen that is produced by the photosynthesis is consumed by the organism that do aerobic respiration.
The reactants of cellular respirationare oxygen and sugar, which are theproducts of photosynthesis. ... When plants are placed in darkness, cellular respiration continues, using ATP to convert sugar into ADP and releasing carbon dioxide. Photosynthesis stops in the absence of light energy.
