Mainly because, nature hates a vacuum. When a certain species drops in numbers, often another, similar species takes over the niche vacated. A good example is the northern spotted owl. As its numbers declined, a close relative, the barred owl, has became more common in the Northwest, displacing the northern spotted owl in many areas.

Yes. All animals have the potential of becoming extinct, especially those that are on the endangered, critical or threatened species list.
What would happen if the Indus river dolphin were to become extinct?
The prey species of the river dolphin, such as fish and shrimps, would suddenly boom and dominate the ecosystem as there would be no predator keeping their populations in check. Whatever those prey species feed on would suddenly decrease as there would be more organisms feeding of it. When one species becomes extinct, it can cause other species to also become extinct. However hopefully the ecosystem returns to an equilibrium eventually. Hope this helps!

What needs to be done about it?

How do scientists know that KT extinction took place?
When we see that there are fossils found in a certain geological layer, which are evidence that a certain species existed at that time, and then in the next geological stratum we no longer find those fossils, and there is no evidence that the species which used to exist still exists, we infer that the species became extinct. If a whole lot of species become extinct at approximately the same time, we call that an extinction event, such as the KT extinction.
What does it means if a species is extinct?
Extinct usually means that no more individuals of the species that are capable of reproducing are still alive. If there are any individuals of the extinct species still alive, since they cannot reproduce for some reason, they are the last generation.
What Percent of animals have gone extinct over the history of earths existence?
Countless thousands of species went extinct before man every showed up on earth. The difference is: Since we weren't here to screw anything up, it was a natural part of nature. Now even today, the great majority of species facing extinction are there due to no fault of man's - nature is continually extincting species and replacing them with new ones, man or not. But some species are definitely near the brink because of man, and those are the ones we are working hardest to save. For if they become extinct, it won't be natures doing - it will be our fault.
Why some species have survived the through ages while some have become extinct?
Some animals are better at adapting to changing conditions and circumstances. Those that can adapt survive when conditions change, others die because they don't have the ability to adapt.

Why do animals feel the need to breed if all it does is create competition for food and they leave offspring as soon as they can fend for themselves then why to they do it in the first place?
Survival of the species ! Lots of animals are prey to others - if they didn't reproduce to replace those lost to predators, they'd go extinct !
