Question

human beings and cow, both are vertebrates but eats grass and human don't explain why​

Answer 1

U r correct that both are vertebrates but their internal structures r different. Grass contains cellulose which is difficult to digest. Human beings don't have such an efficient suggestive system that they can digest cellulose. But cows have an efficient digestive system which can digest cellulose easily. This is the main reason why cows eat grass but human beings don't.
