Animals have a circulation that humans don't have
They have appendix as a working organ, its vestigial in humans.
Humans lack the necessary enzymes to break down and digest the cellulose in grass, which makes up the majority of its structure. Additionally, grass does not contain a high enough concentration of protein to sustain human dietary needs. Animals, on the other hand, have evolved to have the necessary enzymes and digestive systems to break down and extract nutrition from grass. Many herbivorous animals, such as cows and sheep, have complex stomachs that allow them to ferment and extract nutrients from grass.
T-rex did not have two stomachs. Today, ruminants (grass eating animals such as cattle) have two stomachs in order to better digest the grass they eat, which is very difficult to digest.
Ruminants are animals that eat grass. They are specially adapted to digest the cellulose found in grass by having large stomachs filled with fermenting bacteria.
Animals that eat grass include cows, sheep, horses, goats, and deer. Grass is a primary food source for herbivores, providing them with essential nutrients and energy. These animals have evolved to efficiently digest and derive nutrition from grass.
Yes, grass does have seeds. Grass seeds are dispersed through various methods such as wind, water, animals, and human activities.
Grass does produce oxygen from the air living animals and human breathe out called carbon dioxide.
A rumen.
If a human were to eat the same diet as a cow, then it will go through faster in a human than in a cow. Thus, a human on a vegetarian diet will digest food faster than a cow would on grass.
Cow's graze on grass to feed as they can easily digest grass.
herbivores have special digestive system which allows them to digest grass . earlier humans were also able to eat grass when there was no tradition or science to eat cooked food .but with the increase of science, humans started eating cooked food while ignoring raw food like grass,leaves. with time,human's digestive organs that were used to digest raw food (grass,leaves) became extinct.that is y now humans are not able to digest grass
*eat They can, they just cant digest it
