Fun Online Polls: Carnivores & The collapse of civilisation

The responses to last week's Fun Online Poll were as follows:

Is it possible to a have an eco-system where all the animals are carnivores?

Yes - 15% votes
No - 74% votes
Other, please specify - 11%

Clearly the answer is "no", well done 74% of us.

As DP said, "Such an eco-system would reduce to a snake eating its own tail."

There is not earthly way that you can explain how the answer could be "yes" and there is no third possibility.
