Answer:
1
Step-by-step explanation:
photosythesis h20+co2->c6h1206+o2
cellular respiration o2+c6h12o6->h2o+co2+atp
o2= oxygen
c6h1206=glucose
h2o=water
co2= carbon dioxide
atp=energy
reactants are on the left side of the arrow
products are on the right side of the arrow
so looking at C.R.equation on the right side (products )has h2o+co2+atp
