Researchers have accepted three levels of biodiversity, namely genetic biodiversity, species biodiversity, and ecosystem biodiversity. All three levels are interrelated.
Genetic diversity includes variety at the level of genes. It is measured at various levels like population, species, community, and biome.
Species diversity includes variety in the species. It is the easiest method of studying diversity. Each species has a particular role in the ecosystem.
Ecosystem diversity includes diversity that deals with species distribution, community patterns, the role of key species and species interactions.
Thus, the correct answer is option E.
