What is the potential consumer level of the Zebra Spitting Cobra when it eats a frog that consumes insects?

Tertiary or quaternary consumer

The classification of a consumer level depends entirely on the trophic position of the prey item being consumed. When the *Naja nigricincta* consumes a frog, its level depends on what the frog ate. If the frog acted as a primary consumer (by eating plants or herbivores—though frogs typically eat insects), the cobra would be at the secondary consumer level. However, if the frog acts as a secondary consumer by eating insects (which are often primary consumers of plant matter), the cobra consuming that frog is functioning as a tertiary consumer. If the prey sequence extends further, the cobra occupies the quaternary level. The broad inclusion of prey across multiple feeding levels places the snake in this variable position within the food web.
