Answer: Food chain can be defined as an order of transfer of energy in the form of food among organisms at different trophic levels.
Explanation:
The plants, animals and decomposers are components of the food chain. The biomass in plants and animals after their death or death of any part of them get converted into simpler molecules by the action of the decomposers.
Decomposers break down the complex organic molecules into simple molecules and further break them to atomic levels, which can again absorbed by the plants through soil.
