19. The chemical equation for photosynthesis is _CO2 (g) + _H₂O (1)→ __C6H1206 (s) + (C6H12O6 is glucose, the simplest sugar) a. Balance the chemical equation above by filling in the blanks. b. According to onetreeplanted.org, the average tree (across all climates and sizes) removes 10 kg of carbon dioxide from the atmosphere every year. Based on this, what mass of glucose is produced annually by the average tree? O2 (g) c. Teak is a common species of tropical tree. The graph below shows the amount of CO₂ absorbed by teak forests in tons of CO₂ per hectare of forest per year, according to the climate region where the forests are found (dry = low rainfall, humid=high rainfall). Looking at your photosynthesis equation again, what does this data suggest about which reactant is the limiting reactant for teak trees? Explain. C Teak Carbon sequestration rate (tons CO₂ ha -1yr -1) 10 10 20 Tropical humid Tropical dry Aboveground biomass, 0-20 years Belowground biomass, 0 -20 years
