The reactants of photosynthesis include
a oxygen.
b
chlorophyll.
C
carbon dioxide.
d two of the above

Option C) Carbon dioxide

Explanation:

During photosynthesis, atmospheric carbon dioxide and water is reacted to give sugar molecules in the presence of sunlight trapped by the green coloured pigment named chlorophyll present in the chloroplast. At the end oxygen is given off as by-product

The equation is shown below:

6CO2 + 6H2O ---> C6H12O6 + 6O2

Thus, carbon dioxide is a reactant alongside water

it's anything that aren't producers and consumers.
