I have to make a biome report for my biology class. I have to make and label a energy pyramid, and list all the levels (producer, primary consumer, etc). So as I label, I've gotten to a 4th level of consumer, which isn't the apex level (the highest level. What would I call this 4th level? The 3rd level is tertiary, but I have no idea what the 4th level is. Can any of you guys help me out?

So my question is. Can Pre-Cum fluid pass through my underwear, my jeans, onto and through her jeans, through her underwear, and impregnate her?
It would be called a quaternary consumer. Don't forget that you will probably also have to include an energy source (sun) for producers.

Here is a list of everything coming after quaternary: http://www.oxforddictionaries.com/page/124
