Extreme radiation events of the organisms that survive the mass extinctions as they evolve to occupy the niches abandoned by the organisms going extinct.
The disappearance of a species from all parts of an environment is known as extinction. This occurs when the last existing member of a species dies, leading to its complete disappearance from the planet. Extinction can be caused by various factors, including habitat destruction, climate change, pollution, and hunting.
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.
Mass Extinction
usually an asteroid decintigrates before it hits the earth. If an asteroid hit the Earth depending on its size, the smoke and debris of the impact would block out all sunlight to Earth. It would become unbearably cold and most life would die out. This is a theory of how the dinosaurs went extinct.this is right
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.
Every animal is a part of the food chain, so mass extinction can have very bad consequences for the species that survive. The surviving species must learn to work around the animal that has recently become extinct.
animals that depended on a species for a food source or some other need will not be able to get that need if that species is extinct, and will either have diffuculty surviving, or will go extinct.
During: Lots of screaming. After: Much, much less screaming.
This would be called a mass extinction or mass die off.This would be called a mass extinction.
A mass extinction.
The death of every member of a species is called extinction. When a large number of different species is dies out at the same time it is called mass extinction.
Life continued to exist after mass extinctions due to the resilience and adaptability of certain species that were able to survive in the changed environment. These surviving species were able to evolve and fill ecological niches left empty by the extinction event, allowing life to continue and diversify over time.
Macroevolution The development of a new species is called speciation.
Evolution is the term that describes development of new species and mass extinction. Over time all living thing have evolved.
New species that form right after a mass extinction
new species that formed to have more space
