Serial Symbiosis

How is the process of serial symbiosis still ongoing?

Would lichen be an example?

Serial symbiosis is a new term to me, maybe someone can enlighten me on this. However lichens are a good example of a symbiosis haveing a mycobiont and phycobiont coexisting to benifit one another. By the way, I read somewhere that a lichen does not necessarily have to have a phycobiont or algae to form. Has anyone else read or heard of this? :)

Hmm... It doesn't have to have an algae, it can also form between some species of cyanobacteria and a fungus. But you do need someone to "make the food"

I only have one reference publication on lichens and I do not recall it saying anything similar to that. I believe I read that on some web site. However I do not rely on web sites, with a few exceptions of course, for factual information. Some sites are thrown together just for the sake of having the site up and on the web. I have found lots of misleading information on some.

However I do agree, at present, that there must be a phycobiont of some sort, either algae or a cyanobacteria to manufacture food :)

Believe me, it's true, i read it in the campbell book i think. Generally, it's an algae, but in some cases it can be a cyanobacteria
