Solution

The correct option is A 0.1
As per the 10% Law of energy, only 10% of the energy gets transferred from one trophic level to the next. So, if the producers has 100 kcal of energy, the primary consumer will get 100 × 10100 = 10 kcal.

Similarly, if primary consumers has 10 kcal, secondary consumer will get10 × 10100 = 1 kcal.

Similarly, if secondary consumers has 10 kcal, tertiary consumer will get1 × 10100 = 0.1 kcal..
