Which of these choices is not a natural factor that may introduce species into new habitats?huntingstormocean currentclimates shift

To determine which option is not a natural factor that introduces species into new habitats, let's analyze each choice:

1. Hunting: This is an activity carried out by humans and is not a natural factor. Human actions can introduce or remove species but hunting itself does not facilitate the natural introduction of species.

2. Storms: Natural disasters like hurricanes or storms can disperse species across various habitats, facilitating the movement of organisms that might otherwise be isolated.

3. Ocean currents: These are natural phenomena that play a crucial role in transporting organisms, particularly marine species, across vast distances, facilitating their introduction into new habitats.

4. Climate shifts: Natural changes in climate can alter habitats and thus allow species to expand their range into areas that were previously unsuitable due to temperature or other environmental factors.

Conclusion

The correct answer is hunting, as it is a human-induced activity rather than a natural factor affecting the introduction of species into new habitats.
