Solution

The correct option is D I, II and III
  • 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.
