The pattern of species diversity decreasing with latitude from the equator to the temperate zone is known as the latitudinal gradient of diversity. This pattern is well-documented in both terrestrial and marine ecosystems and is thought to be due to a combination of factors such as climate stability, productivity, and historical factors. Therefore, choice B is the correct answer.
