Identify the correct sequence for flow of energy in a food chain:

The correct answer is: Producers→ Consumers →Decomposers

Producers in an ecosystem produce food. The producer is mostly the vegetation present in the ecosystem. Producers are fed upon by herbivores which in turn are fed upon by carnivores. The carnivores are decomposed to complete this ecosystem. Hence, the correct sequence for the flow of energy in an ecosystem is:
Producers→ Consumers →Decomposers
