RE-NEET 2026 Botany Energy Flow in Ecosystems Multiple Correct Question
Which of the following statements are correct? (a) Energy flow from producers to consumers is unidirectional (b) Energy pyramid can never be inverted (c) Transfer of energy follows the 1% law Choose the correct answer from the options given below:
(a) and (b) only
(a) and (c) only
(a), (b) and (c)
(b) and (c) only
Correct Answer
Detailed Explanation
The correct answer is A) (a) and (b) only.
The principle here is that energy flow in an ecosystem is unidirectional, moving from producers to consumers, which supports statement (a). Statement (b) is also correct because energy pyramids typically cannot be inverted; they illustrate the decreasing energy available at each trophic level.
Statement (c) is misleading; while energy transfer is inefficient, the "1% law" is not a standard term in ecology. It may confuse the concept of energy transfer efficiency, which is generally much lower than 1% at each trophic level. Thus, options that include (c) fail to recognize the inaccuracies in that statement.
