Final answer:
Secondary consumers are found on the third level of an energy pyramid. They are typically carnivores that consume primary consumers.
Step-by-step explanation:
Secondary consumers, those that feed on primary consumers, are found on the third level of an energy pyramid. In an energy pyramid, each step is known as a trophic level. The first trophic level is composed of producers (such as plants or phytoplankton), followed by primary consumers (herbivores) at the second level. Secondary consumers are typically carnivores that eat the primary consumers and are positioned at the third trophic level. Hence, the correct answer to the question is B) Third.
