∙ A food chain refers to the order of events in an ecosystem, where one living organism eats another organism, and later that organism is eaten by another larger organism.
∙ The flow of nutrients and energy from one organism to another at different trophic levels forms a food chain.
∙ It starts with energy from the Sun which is taken by autotrophs (producers) who can prepare their own food.
∙ Primary consumers are herbivores and they feed on plants. Secondary consumers are organisms that feed on primary consumers. Tertiary consumers feed on primary or secondary consumers.
∙ Based on this the correct order will be:
Grass → Grasshopper → Frog → Snake → Eagle
