In this model food web, plants produce seeds, mice eat only seeds, snakes eat only mice, and eagles eat only snakes; nothing in this web eats the eagles. What role do the eagles have here?

Բացատրություն

The eagles eat snakes, which are secondary consumers, so the eagles sit one level higher as tertiary consumers, and nothing preys on them in this web. Secondary consumer fails because that position belongs to the snakes.
