Question

Can we survive on grass or raw leafy vegetables. Give reason

Answer 1

Answer:

Explanation:

No we can't as our body or rather our digestive system doesn't have the digestive enzyme cellulose to process grass during digestion and obtain energy. Human beings are omnivores and thus don't possess all traits of a herbivore like the one I mentioned (absence of cellulose) and thus cannot survive on grass and raw vegetables for a long time.
