the smaller the habitat, the greater the species diversity
|
|
|
the larger the habitat, the greater the species diversity

Detailed explanation-1: -The relationship between habitat size and species diversity is that the smaller the habitat, the less diversity of species there will be. The smaller the “island, ” the fewer species can live there, the smaller their populations can be, and the more vulnerable they are to further disturbance or climate change.
Detailed explanation-2: -Area increases diversity because a larger plot is likely to have more habitats, hence niches, to support a greater variety of species.
Detailed explanation-3: -Habitat diversity is known to affect species richness independent of area per se (Williams 1964; Connor and McCoy 1979); everything else being equal, the more habitats there are in a given territory, the more species there are to be found.
Detailed explanation-4: -Species diversity is higher at the equator than at the poles. In biological terms, this is referred to as the latitudinal diversity gradient (LDG), in which the number of species increases from the poles to the Equator. This ranks among the broadest and most notable biodiversity patterns on Earth.
