Answer:
D. Cellular respiration releases oxygen and photosynthesis releases carbon dioxide
Due to the bad trophic efficiency transfer, there is a loss in the consumption of most energy to cellular respiration at trophic levels. It also loses energy to heat, metabolism and other subsistence for biomass production. There is a higher energy loss when it is at higher trophic levels.
C, energy
to regenerate ATP is the chemical energy stored in food like glucose
