Answer: The correct answer is Producers.
Producers occupy the first trophic level in a food chain that begins the process of energy flow in an ecosystem.

They convert solar energy into chemical energy (ATP and NADPH) that is finally utilized in the formation of food (carbohydrate).
Example of producers- Green plants and algae.
