Answer:
F
Step-by-step explanation:
It occupies both the third and fourth trophic levels. i.e
1st trophic level: Producer(plants)
2nd trophic level: Plant eaters (B & C)
3rd trophic level: Secondary consumers (E & F)
4th trophic level: Tertiary consumers (H & F) (they both feed on E which is a secondary consumer)
Thus F is both a secondary and tertiary consumer.
