The rate of extinction is the number of species that become extinct over a given period of time.
Think about it like a game of musical chairs. In this game, the chairs are habitats and the players are species. As more and more chairs (habitats) get removed due to various reasons like climate change or deforestation, more players (species) lose their spots and 'go out' or become extinct.
Endangered Species: These are species that are at risk of becoming extinct because they either have very few individuals left or face serious threats to their survival.
Biodiversity: This refers to the variety of life in an area determined by the number of different species present.
Mass Extinction: This is an event where a large percentage of all living species become extinct in a relatively short period due to some catastrophic event or widespread environmental change.
