Statement II: Ecosystems are exempted from 2nd law of thermodynamics.
In the light of the above statements, choose the most appropriate answer from the options given below:

- BBoth statement I and statement II are incorrect
- CStatement I is correct but statement II is incorrect
- DStatement I is incorrect but statement II is correct
Correct answer
C. Statement I is correct but statement II is incorrect
Step-by-step solution
Sun is the only source of energy for all ecosystems on Earth, except for deep sea-hydro-thermal ecosystem. The energy flow is unidirectional from the sun to producers and then to consumers. Ecosystems are not exempted from the second law of thermodynamics. They need a constant supply of energy to synthesise the molecules they require to counteract the universal tendency towards increasing disorderliness.
