yes
A cow grows in the same way many other mammals grow. They are born, they walk, eat, drink, and get larger as time goes on, and eventually they die.
A cow needs to eat food for the same reason you need to eat food: to live and be able to function. If you or a cow does not nor cannot eat food, you or that cow will starve to death, or become so thin and weak that you will not be able to move or function properly to survive.
Yes because you walk on it sometimes eat it well... only bugs
Cows don't eat such a thing as "lunch." They eat whenever they want, no matter what time of the day it is.
They don'y always eat all the time. They get their breaks every now and then to sleep, chew cud, walk to get water and mineral, etc. But as far as every day 365 days a year it's the same reason that we "always" eat: It's a matter of life or death if one does not eat, especially for a cow. Eventually if it is not fed on a regular basis (i.e., not at all) it will perish. And no producer wants that to happen.
The exact same thing that any "normal cow" would eat: grass, hay, silage and grain.

they can both eat and walk
No.
There's no such thing as an "organic cow." A cow is a cow, regardless. She will eat what "normal" cows eat, which is defined in the related question posted below.
No, a cow will not eat meat, although there will be some curious cow that would probably try it, cows do not and will not eat meat.
No, never. Cow paddies are cow feces.
