Correct:
A
Explanation
A food chain represents the linear flow of energy and nutrients from one organism to another within an ecosystem. It typically starts with a producer and ends with a top predator.
- Option A: Grass (Producer) → Goat (Primary Consumer/Herbivore) → Human (Secondary Consumer/Omnivore). This represents a correct and logical flow of energy.
- Option B: Elephant and Goat are both herbivores; they do not consume each other, and the sequence does not start with a producer.
- Option C: Snakes do not eat grass, and tigers do not typically prey on snakes in a standard terrestrial food chain.
- Option D: While these organisms can form a chain, the order is incorrect. A valid sequence would be Grass → Insect → Frog.
