I am a brewer, so yeast for beer and yeast for food are slightly different, but the principle is the same.
Yeast need oxygen to reproduce, but not to ferment. This is where your bubbles come from - the release of CO2. When you add sugar to your yeast culture, you make the yeast all happy, because then they have something to eat off of. This speeds up reproduction, and(in beer) leads to the fermentation process, in which your sugars are converted into alcohol.

The yeast needs the sugars to feed itself. When you activate your yeast adding a pinch of sugar will make it grow.

what a lot of people dont realize is that yeast is not "activated" by the sugar. sugar only helps feed it after it is activated. in order to first activate your yeast you need to mix in 105-110 degree water or milk or liquid it calls for. any hotter it will kill the yeast and not rise at all and any colder it wont activate at all. you not necisarially feeding it with sugar directly. most breads i bake are fed by the flour and creates carbon dioxide as it rises. then you have to punch down the dough to mix the heat the activated yeast and carbon dioxide. then you cut the rolls or loaves, let proof again and bake away! any good recipe should explain all the proper steps to take.

To feed the yeast. Yeast needs to feed to grow. You need yeast to grow to help rise your bread (or whatever) Salt will kill the yeast which is why it is added with the flour and such after the yeast has risen for a while.

Yeast is a living organism and you feed it sugar - it thrives on sugar and starts growing and your buns rise

In few words...specific. or juice or in spite of. Yeast eats sugar to make alcohol in fewer words. only provide it time to ferment. in many circumstances a week. Beer and different alcohols significant factor is water w different stuff further.

yeast is an active culture and sugar is food for it.

it activates it, because without the sugar its inert. the sugar is food for the yeast.
