Which organism is typically a primary consumer?

Which organism is typically a primary consumer?

• A. Grass (producer)
• B. Rabbit (primary consumer)
• C. Hawk (tertiary consumer)
• D. Fungus (decomposer)

Answer: (B)

Primary consumers are herbivores that eat producers, the plants that capture energy from the sun. Grass uses photosynthesis to store energy, so it’s a producer. The rabbit eats the grass, placing it at the first trophic level of consumers—the primary consumer. The hawk would be higher up the chain as a tertiary consumer, feeding on other animals. Fungi act as decomposers, breaking down dead material rather than directly feeding on living producers. So the rabbit best fits the role of the primary consumer.
