प्रश्न
“The energy flow in the ecosystem follows the second law of thermodynamics.” Explain.
उत्तर
According to the second law of thermodynamics, every activity involving energy transformation (According to the first law energy can be transferred and transformed) is accompanied by the dissipation of energy as heat and only a part of it is used in building up tissues in an organisms.
This trapped energy as biomass is transferred to the next trophic level. According to Lindman law, only 10% of the stored energy is passed from one trophic level to successive trophic levels.
