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 Ans. from the options given below:
Options
A.Both statement I and statement II are correct
B.Both statement I and statement II are incorrect
C.Statement I is correct but statement II is incorrect
D.Statement I is incorrect but statement II is correct
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 synthesize the molecules they require to counteract the universal tendency towards increasing disorderliness.
