Answer:
1st is correct
Explanation:
At its simplest, a dog's digestive system is a long tunnel that runs from their mouth to the anus. Food goes in at the mouth and travels through this tube and at various stages is broken down and either absorbed into the body or excreted as waste at the anus.
Energy is lost at each trophic level.
The average daily dietary fiber recommendations are 38 grams and 25 grams for male and females respectively. Dietary fiber is the indigestible portion of food that is usually derived from plants. It includes soluble fibers found in peas, beans, apples among others and the insoluble fiber, which promotes the movement of material through the digestive system and increases the bulk of the stool.
The answer to that would be true.
