Which one of the following is the correct sequence of a food chain?
Pick an option to check yourself. The answer stays hidden until you attempt.
• Correct Answer: A
• The correct marine food chain sequence is: Diatoms (phytoplankton/producers) → Crustaceans (zooplankton/primary consumers) → Herrings (small fish/secondary consumers).
• Energy flows unidirectionally from producers to higher trophic levels; reversing the order violates trophic logic.
