Explanation:
photosynthesis and cellular respiration make ATP, the main energy source
We produce carbon dioxide, plants take it in for photosynthesis.
-
The beginning products (plants take these in to start photosynthesis) are h2o and co2

So you could say carbon dioxide is a beginning product in photosynthesis.
Hope this helps!
