16) Take all the organisms above and put them all in their proper tropic levels below.
17) On the right side of the pyramid, assume that the top level organisms obtain 15 Kcal of
energy. Figure out the amount of energy for the rest of the tropic levels
Below is a list of 10 organisms and what they eat. Create a food web on the right side
of this paper. Spread your organisms out so your food web can be seen and properly
labeled.
