Question

The energy flows from autotroph to heterotroph.

• A. True
• B. False

Answer 1

Answer: (A)

Energy flow always occurs from a lower trophic level to a higher trophic level. Autotrophs are the producers and they occupy the first trophic level. Heterotrophs are consumers which occupy subsequent trophic levels as primary, secondary and tertiary consumers. Thus, energy transfer takes place from autotrophs to heterotrophs.

Hence, the statement given in the question is true.
