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.
The effect of mass extinction is extinction, death of a mass
Mass 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.
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.
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.
Species can change is there is a mass extinction or if the type of species changed the type of climate or terrain which would would make the species evolve to its new environment so that it can survive.
During: Lots of screaming. After: Much, much less screaming.
One gradual change that can cause a mass extinction is climate change. If the Earth's temperature rises or falls significantly over time, it can disrupt ecosystems and lead to the extinction of many species that are unable to adapt quickly enough to the new conditions. This can result in a cascading effect on other species within the ecosystem, ultimately leading to a mass extinction event.
This would be called a mass extinction or mass die off.This would be called a mass extinction.
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.
Macroevolution The development of a new species is called speciation.
