Final answer:
A predatory wasp that exclusively consumes herbivorous ants is a carnivore and is classified as a secondary consumer in the third trophic level. Option d is the answer.
Step-by-step explanation:
A predatory wasp that feeds exclusively on herbivorous ants would be an example of a carnivore; this is because it consumes other animals. Specifically, in this instance, since the wasp is consuming herbivorous ants, which are primary consumers, the wasp would be a secondary consumer. The correct position of this wasp in the food chain or food web would therefore be as part of the third trophic level, which includes secondary consumers.
