Detailed explanation-1: -Extinction is the dying out of a species. Extinction plays an important role in the evolution of life because it opens up opportunities for new species to emerge.
Detailed explanation-2: -To become extinct is to be gone forever. Even before the arrival of humans on Earth, species became extinct quite naturally. Natural extinction happens when a species declines in numbers gradually but steadily at the end of its evolutionary period on Earth.
Detailed explanation-3: -The species which no more exist on the earth are known as extinct species.
Detailed explanation-4: -As species go extinct, they are taken out of the food chain. Animals that ate the newly-extinct species have to find new food sources or starve. This can damage the populations of other plants or animals. Furthermore, if a predator goes extinct, its prey’s population can proliferate, unbalancing local ecosystems.
