Final answer:
Habitat loss and introduction of exotic species are two natural factors caused by nature that can cause extinctions.
Step-by-step explanation:
The two natural factors caused by nature that can cause extinctions are habitat loss and introduction of exotic species. Habitat loss occurs through deforestation, damming of rivers, and other disruptive human activities, whereas introduction of exotic species can be damaging to islands and lakes. These factors, along with human activities like climate change and overharvesting, contribute to the current high rates of species extinctions.
