Which is the correct sequence in the food chain?

In an ecosystem, the food chain is referred to as a series of organisms, each dependent on the next for its source of food. Each organism occupies a specific place in the food chain that is known as their trophic level. Producers belong to the first trophic level. Herbivores (which feed on producers) are primary consumers, and belong to the second trophic level. Carnivores (which feed on herbivores) are secondary consumers, and belong to the third trophic level. Furthermore, top level carnivores (which feed on carnivores) are tertiary consumers, and belong to the fourth trophic level.

Among the options available, the option that follows the correct sequence of the food chain is where the producer is the grass, which is used as food by the insect, which is then eaten by a bird, which is finally fed on by a snake.
