Answer:

Photosynthesis is a single displacement reaction.

Explanation:

This is the formula for photosynthesis:

6#CO_2# + 6#H_2O# #-># 6#O_2# + #C_6H_12O_6#

During the light reactions, the water molecules' hydrogen ions are separated from the oxygen atoms, which combine to form oxygen gas molecules which are released into the atmosphere as a waste product.

During the Calvin cycle, CO2 and hydrogen ions from the water combine to form glucose #C_6H_12O_6#.
