Yeast is an small animal that eats food like sugar (candy bars,oreo etc) then it farts out a special type of gas. Put yeast in dough eat the sugar in it the releases the gas and makes the dough or bread grow and expand. And we can eat it. Yeast works better in the heat so0 then the bread will expand faster. but not too fast. that why we bake the yeast and dough and at a certain temperature so it does expand to slow or fast.

Why does bread rise when yeast is added?
Yeast is added to bread along with moisture and sugar, and the dough is kept in a moist, warm environment. During this rising time, the yeast consumes the sugar in the dough and release CO2 gas, which is trapped in the dough and causes the dough to rise. When the dough is baked, the yeast is killed, but the bubbles created by the gas remain.

How do the microbes in bread work?
Bread is not "formed" by microorganisms. However, yeast is added to bread dough as leavening. The yeast, consisting of many billions of microorganism, consume and digest sugars in the dough which produces gas. The gas bubbles cause the bread dough to expand or "rise."
Why is yeast added to bread dough and the dough covered with a cloth and set aside for a few hours before baking?
To allow the bread to rise. During the rising process, the yeast produces gases that form bubbles in the dough, making the dough lighter and "fluffier" than it would be otherwise.
Why is yeast added to bread dough and the dough covered with a cloth and set aside a few hours after baking?
The yeast feeds on carbohydrates in the dough and produces Carbon dioxide gas, this is what causes all the little bubbles that are present in bread and what causes it to "rise." It is left for a while in order for this process to happen and is usually allowed to double in size. Bread with no yeast in it is called "unleaven Bread."
