Detailed explanation-1: -According to the second law of thermodynamics, entropy increases when the form of energy changes. The statement means that there is some amount of energy loss as heat to its surroundings during any transformation reaction.

Detailed explanation-2: -The second law of thermodynamics states that every energy transfer involves some loss of energy in an unusable form, such as heat energy, resulting in a more disordered system. In other words, no energy transfer is completely efficient and tends toward disorder.

Detailed explanation-3: -Law of Thermodynamics in the Ecosystem The second law states that there is loss of energy at each step of energy flow.

Detailed explanation-4: -The second law states that if the physical process is irreversible, the combined entropy of the system and the environment must increase. The final entropy must be greater than the initial entropy for an irreversible process: Sf > Si (irreversible process)

Detailed explanation-5: -An ecosystem needs a constant supply of energy to synthesize the molecules they require. In an ecosystem, the energy flow is always unidirectional because as per the law of thermodynamics: reverse flow of energy would put the system in non-equilibrium.
