Which organism in the food web below is likely to store the most energy

I don't know what Worksheet you have and you didn't include a picture. But the most energy is stored in producers like grass or plants the tropic level or energy level is passed ten percent to the creature that consumes it so...
The sun= %100
Producers =%10
Primary Consumers=%1
Secondary consumers=%0.1
Tertiary consumers=%0.01

Hope this helps
