Statement 1 is correct. When one moves from the poles to the equator, the biological diversity typically increases. The equatorial regions have a greater variety of habitats, more stable climates, and a longer evolutionary history, which contribute to higher species diversity.

Statement 2 is incorrect. While it's generally true that species diversity tends to decrease as one ascends in altitude on a mountain (due to changes in temperature, precipitation, and habitat), there are exceptions, especially in regions with complex topography and diverse microclimates. Therefore, it is not a universal trend.
