Detailed explanation-1: -Species can be difficult to find and identify. Species are not evenly distributed globally, among taxonomic groups, or within a given geographic area.
Detailed explanation-2: -Which statement about biodiversity is true? Biodiversity can be measured at different levels including genetic diversity, species diversity, and ecosystem diversity.
Detailed explanation-3: -Species evenness is a description of the distribution of abundance across the species in a community. Species evenness is highest when all species in a sample have the same abundance. Evenness approaches zero as relative abundances vary.
Detailed explanation-4: -For example: In a forest, there may have a large number of different species (high species richness) but have only a few members of each species (low species evenness) In a forest, there may be only a few plant species (low species richness) but a large number of each species (high species evenness)
