Explanation:

D i think because subducing forms metamorphic rock(subduction is where two convergent plate boundries run into each other bringing down rock into the inside of the earth). Check the comments to see if im right

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen
