> a lion who kills and eats an antelope is engaged in a zero-sum interaction

When we apply economic thinking, this interaction is actually not zero sum - antelopes in general benefit from the signal that they need to be faster.

But they only need to be faster to avoid being eaten by lions, so this seems to be begging the question.

I agree that predation is not zero sum.

The antelope loses its life. The lion gains nourishment for a week.

Clearly the total number of utils in the system has decreased.
