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

Explanation:

In an ecosystem, energy transfer between trophic levels follows the 10 - 20% rule. Available energy decreases at higher trophic levels as only about 10 - 20% of energy is passed on from one level to the next. Energy conversion efficiency also decreases at higher trophic levels. Net production of energy is higher at lower trophic levels since producers (at lower levels) capture energy from the sun and start the energy - flow process. All the statements a, b and c are true.

Answer:

D. None of the above
