Why only grass can be digested by herbivores animal why not by human beings explain
Because humans do not have a digestive system adapted to process cellulose. It requires a much longer and larger digestive tract to house the specialized bacteria that do this. There are a few different strategies herbivores use to process plant matter - for example, rabbits pass everything through their digestive system twice. (They eat their own poo after the first pass - they don’t eat it on the second pass through). Ruminants have multiple chambers where grasses are processed in different ways, and a very different digestive pH from ours.
Humans evolved to be predatory omnivores - our digestive systems are adapted to eating a wide variety of different foods, but none of them particularly hard to process - and skewed toward meat (which is the easiest food to digest - hence why carnivores have the shortest digestive tracts).
