I know this question is not related to brewing but I'm sure brewers will be able to answer it better than bakers. I came across a video on how to make sourdough and all the ingredients to make it was flour and water. I am puzzled, because if I'm not mistaken, flour is unmalted grain grounded into a powder which essentially is just starch. How does yeast survive and propagate in sourdough wothout simple sugars?
