Explanation:
There is 10% of total energy in each increasing trophic level. 10,000 / 10 = 1,000 ,so there are 1,000 units of energy in trophic level 2.
1,000 / 10 = 100, so there are 100 units of energy in trophic level 3.
1,000 + 100 units of combined energy would be 1,100 units of energy.
Hope this helps!
