Fiber is the indigestible portion of plant foods. There are two types; soluble which is fermented in the colon into gases and active byproducts, and insoluble which is metabolically inert that absorbing water as it moves through the digestive system. Fiber isn't considered a nutrient since it can't be digested by humans.

The nutrient that is not digested but stimulates intestinal muscle contractions is fiber. Fiber is a type of carbohydrate that may be soluble or insoluble.
Fiber is classified as a "non-essential substance" thus far, as most dietary fiber is not absorbed by the digestive tract. It is not classifed under any nutrient. It does however, aid in absorbing and digesting other substances.Debates are ongoing as to whether or not fiber should be classified as a nutrient in and of itself. Perhaps one day, it will be, but it is unlikely.
yes
Fibre isn't recognised as a nutrient as it is not absorbed into our bodies but it is necessary for our digestive systems to work properly.
