What do living organisms break down polysaccharides into

Polysaccharides are broken down into single sugars called monosaccharides

Polysaccharides are broken down into disaccharides before being further broken down into monosaccharides by living organisms.

One such example is starch, a polysaccharide, which is broken down into maltose, a disaccharide, which is further broken down into glucose, a monosaccharide.
