What is a primary consumer?

• A. Primary consumers eat decomposers.
• B. Primary consumers eat producers.
• C. Primary consumers eat primary consumers.
• D. Primary consumers are producers.

Answer: (B)

In ecological energy flow, producers are organisms like plants and algae that capture energy from sunlight. A primary consumer is the first group of organisms that eat those producers, meaning they are herbivores that feed on plants. For example, a rabbit munching on grass or a caterpillar eating leaves shows this role. Therefore, the correct idea is that a primary consumer eats producers. The other descriptions don’t fit: decomposers feed on dead matter, not live producers; secondary or higher-level consumers eat primary consumers; and producers themselves are the sources of energy, not the consumers.
