we tested glucose and placed different amounts of yeast in the glucose and found that the more yeast you add, the more carbon dioxide gas you will have. why is more yeast able to produce more carbon dioxide through aerobic respiration?

It's a matter of numbers. Yeast are individual organisms, and each produces CO2 at a certain rate. If you have one yeast cell, you get X amount of CO2. Double the number of cells, you should get roughly double the CO2 produced. Triple the number, you should get triple the amount.
This assumes that the amount of sugar, temperature, and other conditions are constant and the same species of yeast is used for all tests.

Because as long as sugars are readily available for consumption, yeast cells greatly prefer fermentation to oxidative phosphorylation and yeast carries out fermentation in the production of ethanol in beers, wines and other alcoholic drinks, along with the production of large quantities of carbon dioxide.

Why do house plants give off oxygen and feed off the carbon dioxide we exhale?
