Fewer Predators
Well, it is possible; however, if this were to happen the predatory species would be at a particular disadvantage given that it would lose that species in its diet. Should that particular species (i.e., the one that went extinct) have assumed a position of importance in the predator's diet, there could be rather disasterous consequences for the latter's continued survival.
No, it is not necessary that all members of a species must be able to reproduce. In species of insects like ants and bees in particular, very few (one per colony) can actually produce eggs. Example:Queen bee Yes of course every birth matters to an animal species especially endangered species such as mountain gorillas and giant pandas. In higher organisms like vertebrates and some invertebrates, reproduction is the method of continuing their lineage.
There are a number of animals that inhabit both deserts as well as rainforests. It would depend upon the particular species of animal. Some would quickly adapt, others might perish.
A gene pool is the set of all genes, or genetic information, in any population, usually of a particular species. Thus the actively interbreeding population of a species is a genetic pool comprising the genes for that species. Should something happen that would separate the breeding population into two populations where the populations could not longer mingle to interbreed, there would now be two genetic pools.
It would depend on the particular species.

Reproduction
competition would be the first thing. Then as the limited resource diminishes members of the species would die or migrate to a new location, but if they all stayed there the species would eventually go extinct.
Fewer Predators
Reproduction. An individual organism does not have to reproduce in order to survive but if the organisms did not produce then the species would die out after just a single generation.
I would say that the role of a species in a habitat would be its "niche"
If there is no reproduction the species will end when those now existing die. If humans stopped reproducing today. Our species would end when the last of us dies.

There are a number of species of rat that live in deserts around the world. It would be a big help if you named a particular species.
