If you are talking about the paper that is Chapter 2 ecology the best I can tell you is that the marmots habitat is pretty weak and can't be that hard for the bear to get to. It's role in the food chain is to eat the grass to supply energy for the bear, or if it lives a happy life and dies of old age or something the decomposer comes in and breaks it down.
The rest of the food chain would collapse and there would be lots of deaths from starvation.
