The death of all the organisms a species?

The death of all the organisms of a species is called extinction. Extinction can be caused by a variety of factors, including natural disasters, habitat destruction, hunting, and climate change. When a species goes extinct, it means that there are no more individuals of that species left alive. This can have a devastating impact on the ecosystem, as it can lead to the loss of important food sources, shelter, and other resources for other species. Extinction is a serious problem, and it is important to take steps to protect endangered species from going extinct.
