Answer:
If a man carried my burden, he would break his back. I am not big but leave silver in my tracks. What am I?
An open ended barrel I am shaped like a hive. I am filled with the flesh and the flesh is alive.
I'm as simple as a circle worthless as a leader; but when I follow a group their strength increases tenfold. By myself I'm practically nothing.
I am enjoyed with a pot and some pointy sticks.
Squeeze me and I cry tears as red as my flesh but my heart is made of stone.
Though not a plant, has leaves. Though not a beast, has spine. Though many wouldn't need this thing, It's more valuable than wine.
