Question

The number of trophic levels in a grazing food chain should be

• A. Zero
• B. One
• C. Two
• D. Two and above

Answer 1

Answer: (D)

Two and above

A food chain must have at least two or more trophic levels. In a grazing food chain, energy and nutrients flow from the plants to the herbivores (that consume the plants) and then to the carnivores or omnivores that prey upon the herbivores. So, the correct option is 'Two and above'.
