What happens to excess carbohydrates in animals? they are stored as fat. they are stored as protein. they are stored as starch. they are stored as sugar.

They are stored as fats because carbohydrates are not made as protien or sugar, there for cancelling those out, animals do not store starch, therefore, the last answer you have to choose from is fats. : )
