Question

Which of the following trophic levels includes a bird feeding on both insects and berries?

• A. Primary consumer
• B. Secondary consumer
• C. Tertiary consumer
• D. Both A and B
  
• E. Both A and C
  

Answer 1

The correct option is D Both A and B

Primary consumers are the organisms that feed on producers. Since the bird is feeding on berries (producer), it is a primary consumer. The organisms that feed on primary consumers are known as secondary consumers. Since the bird is feeding on insects (primary consumer), it is a secondary consumer as well.

Thus, the correct answer is option D.
