If ants get their energy from producers, then, the antlion would be at a trophic level of secondary consumer.
Generally, there are 3 to 4 trophic levels in a typical food chain or web in ecosystems. These are:
- Producers: usually, the green plants or other organisms that are capable of synthesizing their own foods
- Primary consumers: those that feed directly on the producers
- Secondary consumers: those that feed on primary consumers
- Tertiary consumers: those that feed on secondary consumers
Thus, ants getting their energy from producers means that they are primary consumers. An antlion would feed on ants. Thus, the antlion would be a secondary consumer.
