Question

question 4 of 10
a caterpillar eats only plants. a robin eats the caterpillar. what is the role of
the robin in this system?
a. tertiary consumer
b. secondary consumer
c. decomposer
d. producer

Explanation:

• Producers are organisms that make their own food (like plants).
• Primary consumers eat producers. Here, the caterpillar (which eats plants) is a primary consumer.
• Secondary consumers eat primary consumers. The robin eats the caterpillar (a primary consumer), so the robin is a secondary consumer.
• Tertiary consumers eat secondary consumers (not the case here).
• Decomposers break down dead organisms (not relevant here).

Answer:

B. Secondary consumer
