Endemic species are ecologically important for a number of reasons. First, since endemic species have a generally restricted distribution, threats to endemics carry more risk of extinction than for broadly distributed species. Second, according to research done pertaining to endemic species, when an endemic plant species becomes extinct, it takes with it between ten to thirty endemic animal species. Because of this, we can see that the loss of an endemic species indicates a great threat to in an area. All BUT ONE could apply. A) stability B) competition C) the food web D) biodiversity
