Can we survive only on raw, leafy vegetables/grass? Discuss.
We cannot survive only on raw, leafy vegetables or grass because the leaves and grass are rich in cellulose. Cellulose is a carbohydrate that is undigestable for humans due to the absence of cellulose-digesting enzymes.
Other types of nutrients such as proteins, vitamins, minerals, and fats are also required for the human body, which is absent in raw, leafy vegetables and grass. Also, raw vegetables are not easily digestible compared to cooked vegetables.
Explanation:
Animals, fungus, bacteria, non-green plants, and humans can't make food. Indirectly, they eat autotrophs. Green plants capture solar energy and create glucose for food. So, green veggies and grass can help us survive.
