If individuals in a species never reproduce ,it would mean an end to that species on earth
If there were no pioneer species there wouldn't be any species ya see
This frequently happens. Loss of habitat leads to loss of food sources and shelter. Often, when new non-native species are introduced, it is usually the introduced species that thrives and the native species that becomes extinct. Ultimately, what happens is that yet another species gets marked down as extinct, but nothing is done to address the problem. .. On the other hand, would a species "get marked down" if no observation of it is made? would another species benefit from the extintion? would a species that benefits from the the more plentiful food source consider it "a problem"? would another species suffer a change of diet? is there a species that relied on the feces of the extinct species, or the breath of the species, or some intestinal function, or needed the food source to be kept in check that the extinct species was competing for? would another species be able to use the winning species as a food source, or symbiont, or ...
The rodent population would swiftly diminish !
If all individuals in a species were sterile the species would become extinct
Nothing would happen, they are different species and therefore cannot breed.
The species would die out.
One species would be forced to leave.

If species disappeared from an ecosystem the balance in the ecosystem will be altered.
