a
Do yeast consume gases in order to undergo reproduction?
b
Does sugar combine with water to provide energy for yeast?
c
Does water provide yeast with energy to undergo respiration?
d
Do yeast use sugar for energy and produce a gas?

The question that the experiment answers about the flow of matter and energy during fermentation is:
**d) Do yeast use sugar for energy and produce a gas?**
This question directly relates to the fermentation process, where yeast metabolizes sugar and produces carbon dioxide gas as a byproduct, demonstrating the flow of matter (sugar → energy) and energy transformation during fermentation.
**d) Do yeast use sugar for energy and produce a gas?**
