[Eragon] How has the ecosystem of Alagaesia changed with the extinction of dragons and lethrblaka, two Apex predators?

Two apex predators are eradicated. How does the ecosystem change?

It's a complex system. Especially since in the latter years of the dragon riders, there were very few, if any,  "wild" dragons. Dragons wouldn't eat the cattle of the farmers they protect for example.

However, the flourishing of game animals, deer especially, would be expected.  The rise in population of game animals like deer was a good thing for other predators, like wolves (or Urgals if you consider them beasts), though.   

Wolves, Urgals, and people, likely kept the population of other animals from getting too out of control.
