Quizplus · Accepted Answer

The term "trophic level" refers to an organism's position in a food chain, based on how it obtains its energy. At the bottom of the chain are producers (such as plants), which obtain energy from the sun or from chemical reactions. Primary consumers (such as herbivores) feed on producers, while secondary consumers (such as carnivores) feed on primary consumers. Each level represents a different step in the transfer of energy through the ecosystem. Therefore, trophic level is the best answer for this question.
