Final answer:
Habitat loss and disruption of natural disturbances are major causes of species endangerment and extinction.
Step-by-step explanation:
Species Endangerment and Causes of Extinction
There are several factors that can lead to the endangerment or extinction of a species. The primary cause is habitat loss, where species are reduced to small, fragmented patches of habitat. This puts them at high risk of extinction until more suitable habitat is created through ecological restoration. Another factor is the disruption or elimination of natural disturbances that are essential to maintaining certain ecosystems. People dam rivers, clear native vegetation, and settle in these ecosystems, which affects the survival of disturbance-dependent species. Mimicking the natural disturbances is necessary to ensure their survival.
