Arrange the following living things into a logical food-chain sequence from producer to apex consumer. Items: (a) Frog (b) Eagle (c) Grasshopper (d) Snake (e) Grass

Introduction / Context:Food-chain questions place organisms in the order of energy flow: producer → primary consumer → secondary consumer → higher predators.

Given Data / Assumptions:

• Producer: (e) Grass.
• Primary consumer (herbivore): (c) Grasshopper.
• Secondary consumer: (a) Frog (eats insects).
• Tertiary consumer: (d) Snake (eats frogs).
• Apex predator here: (b) Eagle (can prey on snakes).

Concept / Approach:Follow “who eats whom” logically from plant to top predator.

Step-by-Step Solution:

Verification / Alternative check:Each step is ecologically plausible and commonly cited in basic biology examples.

Why Other Options Are Wrong:

• Other orders either place a consumer before its food source or reverse predator–prey relationships.

Common Pitfalls:Confusing which organisms are herbivores vs. carnivores.

Final Answer:e, c, a, d, b
