Dafna11 [192]
All living things are made up of cells. All non-living things are not.

A dill pickle is technically "living" since it was once growing as a plant. Therefore, the dill pickle has cells.

Which level on on the pyramid will have the most amount of energy?
serious [3.7K]

Answer:

<em>Hello, In all the ecological pyramids, producers (organisms that produce their own food) are found at the lowest trophic level. This trophic level contains the highest amount of energy. The energy in each trophic level of an energy pyramid is just 10 percent of the energy in the level below it. (Why is there less energy available at the top of an energy pyramid than at the bottom?) Less energy is available to organisms in the upper levels because each organism releases some of the chemical energy in food to the air as thermal energy. Less total energy is available with each step up energy pyramid. Hope That Helps!</em>
