Detailed explanation-1: -There are two constituents of species diversity: Species richness: Number of different species present in an ecosystem. Tropical areas have greater species richness as the environment is conducive for a large number of species. Species evenness: Relative abundance of individuals of each of those species.
Detailed explanation-2: -Ecosystems that have high levels of biodiversity have a large number of species, complex food webs, a variety of ecological niches, increased genetic diversity, and abundant resources.
Detailed explanation-3: -Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.
