Topic: Nutrition in Animals

Answer 1

No, Humans cannot survive only on raw, leafy vegetables, or grass. It is because the grass is rich in cellulose, which is a type of carbohydrate that humans are not able to digest due to the absence of cellulose-digesting enzymes.

Answer 2

We cannot survive only on raw, leafy vegetables/grass, because we cannot get all required nutrients, such as carbohydrates, proteins, lipids, vitamins and minerals, from them. Moreover raw vegetables may not be digested easily as compared to cooked vegetables.
