Yeast Grows much better in sugar water. They are micro organisms that need the sucrose in the sugar to activate and grow, without the sugar very little would happen. If you used salt water it would most likely kill the yeast.
Because yeast needs to have food just like us to grow, and sugar is that food.
Sugar makes yeast grow fastest when added to it with warm water
Sugar is a necessary food source for yeast to grow and ferment. When yeast consumes sugar, it produces carbon dioxide and alcohol, which are responsible for fermentation in bread-making and alcohol production.
warm water - yeast needs warm water to become active. suger is the yeast's food .it gives the yeast the energy it needs to grow. cold water - the cold water kills the yeast (kind of) normal room temperature - the yeast just becomes in active and doesn't react
Yeast is a bacteria that feeds on sugar, which causes the fermentation process. In the process of wine making, grapes have yeast in the skin and sugar in the flesh of the fruit, the yeast then feeds on the sugar in the flesh fermenting the juice and making the wine.
Yeast grows fastest with sugar because it is a simple carbohydrate that can be easily metabolized by the yeast for energy. Honey and syrup may contain other components that could possibly slow down the growth of yeast compared to pure sugar.
The heat provides energy for the enzymes in the yeast to work. If the water is to hot however, the enzymes will be denatured, and the yeast will not grow.

yeast only feeds on things with a sugar ingredent so, sugar feeds yeast, cause it grow.
So that the yeast has food to grow.
