Question

Which of the following statements about energy and trophic levels is not true?
a.
The amount of available energy decreases at each higher trophic level.
b.
The energy conversion efficiency decreases at higher trophic levels.
c.
The net production of energy is higher at lower trophic levels.
d.
None of the above


Please select the best answer from the choices provided

A
B
C
D

Answer 1

B

Reason: (a) and (c) are true — available energy and net production decline at higher trophic levels. (b) is not generally true: transfer (conversion) efficiency is not necessarily lower at higher trophic levels (it’s roughly similar or variable, often cited as ~10% per transfer), so (b) is the false statement.
