Question

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:

पर्याय

• Both statement I and statement II are correct.

• Both statement I and statement II are incorrect.

• Statement I is correct but statement II is incorrect.

• Statement I is incorrect but statement II is correct.

Answer 1

Statement I is correct but statement II is incorrect.

Explanation:

Because energy flows in ecosystems in a unidirectional manner from the sun to producers (plants), consumers, and decomposers and energy is lost as heat at each stage, statement I is true. Because ecosystems follow the second law of thermodynamics, which states that energy transitions are inefficient and move toward greater entropy, Statement II is false. At every trophic level, energy is lost as heat, demonstrating the second law of ecological processes.
