Yes, and No. Cows can survive completely on grass as food, but it would need water too.
Cows are herbivores, not carnivores, thus do not need flesh like that from humans to survive.
So that they had the nutrients and proteins there bodys needed to survive, like how humans eat cows, or cows who eat grass.
Cows can't survive on gas alone. Neither can humans. Both cows and humans need food and water to survive, not just oxygen (which is a gas we breathe).
humans....we eat cows and cows eat grass...
No.
because they don't survive by photosynthesis and do eat grass, which is a producer
Well humans don't eat grass because it just isn't on the food pyramid or anything plus cows and horses eat grass. Plus grass is in the ground and the ground is not clean.
They eat grass . They drink lake water. They eat grass . They drink lake water.
HUMANS. Coyotes (yes, they will eat grass, too!).
Cows are grazers, they eat grass and fertilize the grass with their waste. Grass grows from the cow's waste and the cycle starts over again. In turn, cows produce milk to feed their calves or to feed humans and are slaughtered by humans to provide meat.
Yes, of course, cows and sheep use them as their main nourishment. We humans, however, can't use grass as food.
maybe i have no clue!!!!!!!!!!!!!!!!!!!!!!!!! No, humans have a lot more taste buds than cows, since humans are omnivores and cows are herbivores. Therefore, since humans can eat a much more varied diet, they need more taste buds than cows, which only eats grass.
No, they can only survive on humans living off our blood.
