Most of it gets destroyed on entry, right? No organic matter surviving?

No, most are smaller rocks and generally decelerate to terminal velocity in the upper atmosphere. It’s the big ones that have too much momentum and penetrate further at speed, causing them to go boom.

The underlying reason is that momentum scales with volume but air resistance scales with surface area.
