Question

Which of the following represents the correct sequence of organisms in a food chain?

• A. Grass → Grasshopper → Lizard → Hawk
• B. Grasshopper → Grass → Hawk → Lizard
• C. Grass → Snake → Grasshopper → Frog → Hawk
• D. Corn → Mouse → Snake → Hawk

Answer 1

Answer: (A), (D)

Corn → Mouse → Snake → Hawk

Grass → Grasshopper → Lizard → Hawk
Corn → Mouse → Snake → Hawk

Both these food chains represent the correct sequence of organisms in a food chain. Plants always occupy the first level in a food chain. Herbivores depend on plants for their food. Grasshopper is a herbivore and depends on plants for its food. Lizard, snake and hawk are carnivores and depend on other animals for their food.

The correct sequence for the remaining food chains are:
Grass → Grasshopper → Lizard → Hawk
Grass → Grasshopper → Frog → Snake → Hawk
