XXX: The Fish
Among them there is a division into primary and secondary consumptions as among mammals on predators/herbivores?
YYY: Yes of course
There are very few fish. Mostly they eat invertebrates (already consumptions of the second order), and they are eaten by fish-eating predators, and even there are fish that eat only other, less fortunate fish-eating fish.
The xxx:
That is, can you say that among the fish there are consumptions of 4-5 orders?
Essentially
YYY: May be
And we can say that all these consumption orders cannot in principle be described by discrete mathematics.
That, however, does not deprive the concept of order.

Discreet fishing!
YYY: Better
