GENERAL KNOWLEDGE

Detailed explanation-1: -So, the correct answer is ‘-diversity’.

Detailed explanation-2: -Beta diversity: It is species diversity b/w two adjacent ecosystems and is obtained by comparing the number of species unique to each ecosystem. Gamma diversity: It refers to the diversity of the habitats over the total landscape or a geographical area.

Detailed explanation-3: -Beta diversity refers to the number of species. that differ between two habitats. According to the equilibrium theory of island biogeography, the equilibrium number of species on an island can be determined graphically by examining where. the species colonization and extinction curves cross.

Detailed explanation-4: -Beta Diversity = expression of diversity between habitats. In the example below, the greatest Beta Diversity is observed between Site A and C with 10 species that differ between them and only 2 species in common. Gamma Diversity = landscape diversity or diversity of habitats within a landscape or region.

Detailed explanation-5: -Alpha diversity describes the species diversity or species richness in an ecosystem. It is a small scale measure. Beta diversity describes the species diversity between two ecosystems or communities. It is a large scale measure. Gamma diversity describes the species biodiversity in a large geographic region.
