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 2nd law of thermodynamics.

In the light of the above statements, choose the most appropriate answer from the options given below :

1. Both statement I and statement II are correct

2. Both statement I and statement II are incorrect

3. Statement I is correct but statement II is incorrect

4. Statement I is incorrect but statement II is correct

1 answer

Best answer

Answer: 3. Statement I is correct but statement II is incorrect

Key idea: Energy flow in an ecosystem is unidirectional, and it obeys thermodynamics.

  • Statement I is correct: solar energy captured by producers passes to consumers, and is not returned to the sun.
  • Statement II is incorrect: ecosystems are open systems that need a constant supply of energy to counter entropy, so they are not exempt from the second law.

Option 3.
