which equation represents photosynthesis?
h₂o + o₂ + sunlight → c₆h₁₂o₆ + co₂ + energy
co₂ + h₂o + sunlight → c₆h₁₂o₆ + o₂
c₆h₁₂o₆ + co₂ + sunlight → h₂o + o₂
c₆h₁₂o₆ + h₂o → co₂ + o₂ + energy

Explanation:

Photosynthesis is the process by which plants, algae, and some bacteria use sunlight to convert carbon - dioxide ($CO_2$) and water ($H_2O$) into glucose ($C_6H_{12}O_6$) and oxygen ($O_2$).

Answer:

$CO_2 + H_2O+\text{sunlight}
ightarrow C_6H_{12}O_6 + O_2$
