The energy that enters the food chains, first of all, is light energy from the sun. This energy is assimilated by plants to convert it into chemical energy, through photosynthesis.

When energy flows from producers, plants, to consumers and decomposers, a great amount of energy is lost, in the form of heat energy, due to the metabolism of living beings. Additionally, the second law of thermodynamics states that when energy passes from one form to another it leads to disorder in the system, which would also explain the loss of energy.

The true statement is "Energy enters a food chain as light energy and leaves it as heath energy".
