What is a species that has no more individuals living on earth?

An extinct species is a species that has no more individuals living on earth. Extinction is the natural process by which species become extinct. Extinction can be caused by a variety of factors, including environmental changes, predation, competition, and disease. Some species are more vulnerable to extinction than others. For example, species that have a small population size, live in a specific habitat, or rely on a single food source are more likely to become extinct. The extinction of a species can have a significant impact on the ecosystem. For example, the extinction of a predator can lead to an increase in the population of its prey, which can in turn lead to a decrease in the population of the prey's food source. Extinction can also lead to the loss of important ecological functions, such as pollination and seed dispersal.
