Answer:
According to the second law of thermodynamics
Explanation:
According to the second law of thermodynamics, entropy of a system always tends to increase. It states that none of the process of energy transfer is perfect as part of the energy is always lost as heat during each energy transfer. The lost energy serves to increase the entropy of the system. This is why, only 10% energy of each tropic level is passed to next tropic level and rest is lost as heat.
