A given ecosystem has the following amounts of energy available at each trophic level: Primary producers: 4,000 gC/m2/day; Primary consumers: 480 gC/m2/day; Secondary consumers: 72 gC/m2/day; Tertiary consumers: 24 gC/m2/day.
Does this ecosystem follow Lindeman's Law for ecological efficiency?
a. Yes, the average efficiency is 20%
b. Yes, the average efficiency is 10%
c. No, the average efficiency is 20%
d. No, the average efficiency is 10%

The average efficiency at each trophic level is 10% because there is about 10% of energy is transferred from one trophic level to another. In some trophic levels the efficiency of organisms is 20% but in most of the trophic level has 10% efficiency so that's why the average efficiency is 10%. Yes, this ecosystem obeys the Lindeman's Law for ecological efficiency due to its 10% of ecological efficiency.

Yes, the energy available to all trophic levels is in the average of 10% which

follows Lindeman's Law for ecological efficiency.

Lindeman's Law for ecological efficiency states that the energy transfer from

one trophic level to the other should have a 10 percent efficiency. The

trophic level starts with the primary producers having more energy and the

tertiary consumers having the least amount of energy.

The example given shows that the different trophic levels in the ecosystem

have about 10 percent efficiency during energy transfer and availability.
