• A. Producers
• B. Secondary Consumer
• C. Primary Consumer
• D. Detritivore

Answer: (C)

Energy moves through ecosystems from producers up to higher-level consumers. Producers form the base by making energy through photosynthesis, so the next step up—the second trophic level—is made up of primary consumers. These are organisms that typically eat producers, usually herbivores. That direct feeding on producers is exactly what defines a primary consumer. For example, a rabbit eating grass is a primary consumer. Secondary consumers would eat primary consumers, not producers, placing them higher in the chain. Detritivores feed on dead organic matter rather than live producers, so they don’t fit the description either.
