Which of the following statements is correct regarding the difference ...

Extinction of an organism means that it no longer exists anywhere on the planet.
There are two different types of extinction:

Background extinction

It refers to the normal extinction rate. These are species that go extinct simply because not all life can be sustained on Earth and some species simply cannot survive.

Mass extinction

It is a widespread event that wipes out the majority (over 50%) of living plants and animals.
Mass extinction leads to permanent loss of a major group of organisms
Mass extinction account for all the extinct species on earth.
Mass extinctions can be caused by both natural and human interventions, while background extinctions are generally natural. Hence statement 1 is not correct.
Mass extinction has a greater impact on the ecosystem than background extinction. Hence statement 2 is correct.
Earth has experienced several mass extinctions. The most devastating, perhaps, was the Permian mass extinction 225 million years ago. About 90% of the species living at the time went extinct, including most of the dominant land vertebrates at the time.

Extinctions occur continually, generating a "turnover" of the species living on Earth. This normal process is called background extinction. Sometimes, however, extinction rates rise suddenly for a relatively short time — an event known as a mass extinction. Mass extinctions kill off many species, but the empty niches left behind may allow other lineages to radiate into new roles, shaping the diversification of life on Earth.
