NEET BIOLOGY

Detailed explanation-1: -“Species diversity is defined as the number of different species present in an ecosystem and relative abundance of each of those species.” Diversity is greatest when all the species present are equally abundant in the area.

Detailed explanation-2: -Species Diversity is simply the number and relative abundance of species found in a given biological organisation (population, ecosystem, Earth). Species are the basic units of biological classification and hence, this is the measure most commonly associated with the term ‘biodiversity’.

Detailed explanation-3: -Species abundance is the number of individuals per species, and relative abundance refers to the evenness of distribution of individuals among species in a community. Two communities may be equally rich in species but differ in relative abundance.

Detailed explanation-4: -Abundance is defined as “the measure of the number or frequency of individuals of the same species, ” whereas diversity demonstrates the “number of species present (species richness) and their abundance (species evenness) in an area or in a community” (Booth et al., 2003).

Detailed explanation-5: -biodiversity, also called biological diversity, the variety of life found in a place on Earth or, often, the total variety of life on Earth. A common measure of this variety, called species richness, is the count of species in an area.
