Given below are two statements:
Statement I: In ecosystem, there is unidirectional flow of energy of sun from producers to consumers.
Statement II: Ecosystems are exempted from 2 law of thermodynamics.
In the light of the above statements, chocse the most appropriate answer from the options given below:
- A
Statement I is incorrect but statement II is correct
- B
Both statement I and statement II are correct
- C
Both statement I and statement II are incorrect
- D
Statement I is correct but statement II is incorrect
Statement I: The sun is the ultimate energy source for almost every ecosystem on Earth, and this energy flows in one direction — sun producers consumers. So Statement I is correct.
Statement II: Ecosystems are not exempt from the second law of thermodynamics. They require a constant input of energy precisely because some energy is always lost as heat (entropy increase), in line with the second law. Statement II is incorrect.
