Educational Uses: Beyond the "cool factor"

As a hgih school teacher Im wondering of lesson planning that could be done around this game, im SUPER STOKED to have found it, but i need to make it usable for a biology classroom.
Thoughts?

We'll be doing more of this in the summer. Currently activities revolve around the idea of having students represented by a card, and then trying to "link" up so that viable food chains can be created. Some suggested ideas also take this a step further by having it work around a race (two teams run to pick up from a pile of cards - first team to "connect" themselves properly win - note that event cards also thrown in so that there is an opportunity to mess up the other team).

Anyway, other ideas are definitely welcome.

p.s. We're also trying to see if there's a feasible way to revamp the website so that the DIY cards can be more easily made (by the students themselves)
