Which of the following describes the term "endemic"?

The term "endemic" specifically refers to a condition or species that is native to and restricted to a particular region or environment. For instance, a plant species that is considered endemic to a particular island means that it is not found naturally anywhere else in the world besides that island. This concept is often used in ecology and geography to talk about species, diseases, and sometimes cultural phenomena that are characteristic of a certain area. Understanding that "endemic" signifies confinement and specificity to a certain region is crucial in distinguishing it from other terms that might suggest broader or different distributions, thereby reinforcing the idea that its defining characteristic is this particular association with a specific locality.
