Well, I can tell you that a non-biological cake is not much edible.\nOther than that, is it possible that you're referring to the "metaphor" (kind of) that depicts Biology as a cake in which the layers are the basic divisions (disciplines like genetics, ecology, morphology, etc.) and the slices are the taxonomical divisions (i.e. all the taxa to which the disciplines can be applied).\nSee the link for an illustration of the concept.

no it doesn't, you can get parasites regardless of your immune system's condition.

Maybe tape worm or pinworm

The food (trophical) chain is based on trophical relationships between organisms (predator-pray) and viruses use human and other animals as hosts not as food. Even other parasites aren't higher than human in a food chain because it's a very complex calculation that has a lot to do with mass and number of organisms belonging to the food chain... And yes, someone was right, there are some animals that could eat a man and they could be higher in a food chain but food chain doesn't describe all the trophical relationships in nature, it's just an example! People (even teachers) often forget that...

Might it be a chafing dish?

Intestinal parasites. Also lots of different diseases could be responsible. See a doctor!

It could be a parasite but it could also be a anal fissure or fistula.\n\nhttp://www.emedicine.com/emerg/topic495.htm

I hate to suggest this, but could they be coming out of you?  Is it possible you've got worms?  Are you losing weight?  Wow, I want to ask no end of questions now, I guess you wouldn't know how you got them?

They are both. There are Good ones and Bad ones. Some parasites such as leeches simply suck your blood out and do nothing for you. Other parasites have what is known as "Symbiotic Relationships" where they help one another. For example, there are birds that nest on alligators. The alligators give the bird safe haven from dangerous predators. The Birds in turn feed on particles of food left in the alligators mouth so they dont suffer from dental problems. They help one another out.

like others have said parasites are definately living things.  I didn't know there was even a debate as to whether virus are living things, I thought it was pretty much agreed upon that they are.  I guess it depends on your definition of life, which is something that's a hotly debated issue.  I don't think there is a clear cut answer myself as far as what should be considered a life form and what shouldn't.

There are indeed parasites that can invade the brain, there is another one called the loa loa worm that is called the eye worm. I have a book with a picture of a work being pulled right out of this guys eye. Anyway is will blind you. And for the parasites in the brain, if someone did get this it is fatal. The good news is you have to go to some really third world countries to get these things.
