Photosynthesis requires an input of energy, while respiration releases energy. Consider a growing tropical rainforest. This rainforest has a much higher rate of plant biomass formation than its respiration rate. Does the rainforest have a higher input of energy or output? A. Input (There is more energy being input through photosynthesis than lost through respiration)

B. Output (There is more energy lost through respiration than gained through photosynthesis)
