Explanation:

1. Most of the energy that isn't stored is lost as heat or is used up by the body as it processes the organism that was eaten.

2. Given energy = 1000kcal,

then after 1st trophic level, it comes to

10/100 × 1000 = 100kcal.

then after 2nd trophic level, it comes to

10/100 × 100 = 10kcal.

Hence, After 2 trophic levels the given energy drops down to 10kcal.
