Explanation:
Detailed explanation-1: -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.
Detailed explanation-2: -The phenomenon where a species that used to exist, does not exist anymore is known as extinction. A species is believed to be extinct when the last living member dies.
