Question

What will be the amount of energy available to the first trophic level 10,000 joule?

Answer 1

First trophic level -- 10,000 J

According to 10 % law,

Only 10 % of a particular trophic level is available to next level.

So for 2nd trophic level the energy available will be -- 10 % of 10,000

10/100 x 10000 = 1000 J
