Question

If the lancet fish never goes to the surface but it has plastic in its gut, that means


it must eat creatures deep beneath the surface that eat plastic.


it must eat creatures that go to the surface to eat plastic.


it actually must go to the surface and eat plastic.

Answer 1

The most logical conclusion is that **it must eat creatures deep beneath the surface that eat plastic.** If the lancet fish never surfaces itself but still has plastic in its gut, the most likely explanation is that it is consuming prey that have ingested plastic, rather than having eaten plastic directly from the surface. This suggests a deeper ecological chain where the plastic is being introduced into the food web.
