Final answer:
Habitat loss, introduction of non-native species, and disease are factors that can lead to species extinction.
Step-by-step explanation:
One of the factors that can contribute to a species becoming extinct is habitat loss and degradation. When their natural habitat is destroyed or altered, it can disrupt the species' ability to survive and reproduce. Another factor is the introduction of a non-native species, which can outcompete native species for resources and disrupt the ecological balance. And finally, disease can also cause the decline and extinction of a species.
