A food chain illustrates the flow of energy in an ecosystem, starting with a producer. In Option A, Grass is a producer (plants), Goat is a primary consumer that eats grass, and Human is a secondary or tertiary consumer that can eat goat. This correctly shows a linear flow of energy from producer to consumers. The other options present incorrect or reversed sequences that do not represent a valid food chain: B) Elephant and Goat both eat Grass, but there’s no flow shown between Elephant/Goat and Grass in the order presented. C) Tiger eats animals, Snake eats animals, Grass is a producer – no correct flow. D) Insect eats Grass, Frog eats Insect, Grass is a producer – the order is incorrect.

– A food chain starts with a producer (organism that makes its own food, usually plants).
– The arrows in a food chain indicate the direction of energy flow (from the organism being eaten to the organism that eats it).
– The sequence is typically Producer -> Primary Consumer (Herbivore) -> Secondary Consumer (Carnivore/Omnivore) -> Tertiary Consumer, etc.

Food chains are simplified models of energy flow in ecosystems. In reality, organisms often have multiple food sources, forming complex food webs. Understanding food chains helps to understand ecological relationships and energy transfer efficiency.
