Mass extinction isn't a natural role in any life-system. They happen as a consequence of some catatrosphic disaster or radical unbalance in the eco-system. As a result of mass extinctions other 'groups' evolve into species that take the place of those exterminated.

∙ 10y agoMass extinctions have the effect of eliminating a large number of species, which leaves a wide variety of niches open to new species. Whichever species survive the mass extinction quickly evolve into many new forms to fill the empty niches. The Permian-Triassic Extinction Event left niches open to the dinosaurs, and the Cretaceous-Tertiary Extinction eliminated dinosaurs, leaving niches open to mammals.

What is cause background extinction?
It is the fate of most living things eventually to go extinct. standard commonplace rate of extinction not associated with a mass extinction.
What is it called in particular when a high percentage of the species on earth dies off at a particular time?
These are called "mass extinctions", and there have been five such events (that we know of) on the Earth. These are generally caused either by astronomical impact events (such as the asteroid that killed off the dinosaurs 65 million years ago) or massive volcanic activity. The causes of these extinctions has been a matter of some dispute, since they happened so long ago.
What might have caused the mass extinction at the end of the paleozoic era?
The mass extinction, known as the Permian extinction, affected both plants and animals on land and in the seas. Scientists do not know what catastrophic events caused the mass extinction, many kinds of organisms suddenly became extinct, as much as 90% of Marine species may have died out.
When was the first mass extinction?
540 million years ago was the first mass extinction
Why did many planets die at the end of the mesozoic?
Scientists believe the Cretaceous-Paleogene extinction event, or the plants dying at the end of the Mesozoic Era, was caused by a massive asteroid/comet impact. The theory suggests that the impact had catastrophic effects on the environment, including an impact winter, which prevented the plants from carrying out photosynthesis.
Why was the permian extinction called the great dying?
The Permian extinction is called the "Great Dying" because it was earth's largest mass extinction which wiped out as much as 95% of life.
How large was the Permian mass extinction?
95 percent of Earth's life was killed by hydrogen sulphide.
What would the impact of earth be if no ozone layer?
If there was no ozone, no life would be there. There would be mass extinction.
How are objects around you affected by mass of earth?
The objects around you and me are affected by the mass of earth by gravity
What is it called when a high percentage of the species on earth dies off at a particular line?
This would be called a mass extinction or mass die off.This would be called a mass extinction.
Is there going to be another mass extinction on earth?
Eventually yes.
When was the most rapid mass extinction?
The fastest extinction of life on Earth occurred 65 million years ago when over 80% of the earth's organisms went extinct. This occurred in a relatively short 2-5 million years,
How do you use the word mass extinction in a sentence?
We are still not sure what caused the mass extinction of the dinosaurs, though an asteroid impact seems to be the popular theory.Scientists believe we may be heading towards another mass extinction event.
An object's mass is affected by earth's pull on it?
no. weight is affected
When was the last mass extinction?
The Cretaceous–Tertiary extinction event 65 million years ago was the last mass-extinction, and many believe that humans are causing a mass-extinction right now.
What is an example of mass extinction?
When the meteorite hit Earth and killed the dinosaurs.
What era ended in the largest mass extinction in earth's history?
Mesozoic
