Question

name & explain type of carbohydrates that can ruminants & not by humans

Answer 1

Cellulose is a type of carbohydrate that can be digested by ruminants and not by humans.
 
Ruminants have a large sac-like structure called rumen between the oesophagus and the small intestine. The cellulose of the food is digested here by the action of certain bacteria which are not present in humans.
