Assertion: The 10 per cent law of energy flow is an absolute rule that applies to all ecosystems.

Reasoning: The 10 per cent law of energy flow is a general rule that applies to most ecosystems. However, there are some ecosystems where the efficiency of energy transfer between trophic levels may be higher or lower than 10 per cent due to various factors such as the trophic structure of the ecosystem, biodiversity, and climate conditions.

If 10 joules of energy is available at the producer level, then amount of energy present at the level of secondary consumers is 

Given below are two statements:

Statement I: In an ecosystem, there is an unidirectional flow of energy from the sun from producers to consumers.

Statement II: Ecosystems are exempt from 2nd law of thermodynamics.

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