Clear bottle
Opaque bottle
Pair 1
Autotrophs in the transparent bottles produce carbohydrates by photosynthesis and consume carbohydrates by respiration.
Autotrophs in the opaque bottles cannot produce carbohydrates by photosynthesis.
Pair 3 Eu

It's darker down here, and the amount of carbohydrates produced may equal the amount consumed.
Pair 4
It may be so dark here that little photosynthesis can occur; consumption of carbohydrates would exceed production.
