(D) connect two otherwise isolated populations.
Because of the warm environment and high primary productivity in the area close to the equator, the tropics typically have higher levels of biodiversity than other parts of the planet. Less than 10% of the earth's surface is occupied by these tropical forest ecosystems, which are home to 90% of all species. The mid-latitudinal belt of all oceans and the shores of the Western Pacific, where the sea surface temperature is highest, typically have higher levels of marine biodiversity.
The variety of species exhibits latitudinal variations. Although biodiversity has been rising over time and tends to concentrate in hotspots, it is expected to slow down in the coming years as a direct effect of deforestation. It includes the biological processes of evolution, ecology, and culture.
