The digestive system converts the foods we eat into their simplest forms, like glucose (sugars), amino acids (that make up protein) or fatty acids (that make up fats). The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body.

Bread mold is the most commonly known mold that grows on bread, pickles, fruits etc. A wet piece of bread is a hot bed for the bread mold to grow.

In few days, you will observe that the whole surface of bread will be covered with it and looks black in color because they have absorptive mode of nutrition in which they break down the carbohydrates into simpler units and feed on them.
