You would expect 25 Kcal of energy stored in trophic level 4.

Explanation:

Energy flow in the ecosystem follows 10% law according to which 10% of the energy in the lower trophic level is transferred to the next trophic level.

In this example grass belongs to the first trophic level, producers.

Energy of grass=25000Kcal

Energy transferred to trophic level 2=10% of 25000=2500

10% of the energy in trophic level 2 is transferred to trophic level 3.

Hence energy at trophic level 3=10% of 2500=250Kcal

Energy transferred to trophic level 4=10% of energy in trophic level 3

=10% of 250=25Kcal

Energy to be stored in trophic level 4=25Kcal

If the grass in this example had 25,000 Kcal of energy,approximately how much would you expect of that energy tobe stored in trophic level 4?
