9. Which practice has been able to save some organisms from extinction?
Archy [21]

The practice that has been able to save some organisms from extinction is cross breeding.

<h3>What is cross breeding?</h3>

Cross breeding is the process of producing separate strains of the same species in order to create new traits.

Living organisms are bound to go extinct when faced by certain unfavorable conditions that cannot be adapted to.

However, the production of resistant strains of the same species of an organism via cross breeding can help prevent them from going extinct.
