3. It is an important part of evolution.
4. Species with characteristics like large body size, small population size, feeding at high trophic levels in the food chain, low reproductive rate, etc., are more susceptible to extinction.
5. Natural, mass, and anthropogenic extinction are the three types of extinction processes.

Mass extinction:

1. Extinction of a vast number of species during a short period of geological time is assumed to be caused by events such as a catastrophic global event or broad environmental change that occurs too quickly for most species to adapt to.
2. There have been five events of mass extinction of species during the extended time (> 3 billion years) from the genesis and diversity of life on Earth.
