In order to answer this, you need to know exactly what a trophic level is.  A trophic level refers to each step of the energy pyramid.  Producers are located at the bottom level and each consecutive level is made up of different levels of consumers.  All energy comes begins at the bottom of the pyramid.  As you go up each step you lose 10% of the energy.

In approaching an essay on this topic, I would consider writing a paragraph for each individual pyramid level.  Describe what organisms you find there and what is happening to the energy at that stage (are they making it, consuming it, or both).
