Which species example is least likely to become endangered? Ujung Kulon National Park, The genetic, species, and ecological diversity of the organisms in a given area, Areas with exceptionally high numbers of endemic species, The importance we place on just knowing that a particular species or a specific organism exists, The irrevocable elimination of species; can be a normal process of the natural world as species outcompete or kill off others or as environmental conditions change, Habitat destruction, Invasive species, Pollution, Population(human), and Overharvesting- the leading causes of extinction, Organisms that thrive in new territory when they are free of predators, diseases, or resource limitations that may have controlled their population in their native habitat, Harvesting so much of a resource that its existence is threatened, Species considered to be in imminent danger of extinction, Species that are likely to become endangered- at least locally- in the foreseeable future, Species that are naturally rare or have been locally depleted by human activities to a level that puts them at risk, Keystone species are those with major effects on ecological functions and whose elimination would affect many other members of the biological community, Indicator species are those tied to specific biotic communities or successional stages or a set of environmental conditions. A perfect example for this would be rock formations into the ocean after a volcanic eruption. Pesticides and other chemicals can poison plants and animals if they are not used correctly.
