This is certainly a borderline question. Googling the question I found a link that says that a shell is an abiotic thing made by something that is biotic. In my opinion, I agree with that. Virtually all aspects of the earth have been shaped by life -- if an empty shell is considered biotic, then so must the O2 in the air, because it was generated by ancient and recent photosynthesis. An empty shell was sculpted by life, and the inorganic (and organic) chemicals within it were put there by a living organism, but now it is simply form and chemicals, both of which are slowly broken down and scattered with time. I vote "abiotic".
