As I was going through a field of wheat,
I found something good to eat;
It wasn't fish or flesh or bone;
I kept it till it ran alone.

What am I?
What is that which, while it lives, constantly changes its habit, that is buried before it is dead, and whose tomb is valued wherever it is found?See answer
