The 10 percent law of energy flow is a general rule that applies to most ecosystems, but it is not an absolute rule that applies to all ecosystems. The reasoning correctly explains that there are factors that can influence the efficiency of energy transfer between trophic levels, but this does not contradict the assertion that the 10 percent law of energy flow is not an absolute rule. Therefore, Both assertion and reasoning are true, but the reasoning is not the correct explanation of the assertion. Hence, the correct answer is option 2.
