Answer 1

Answer: (E)

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.
  

Thus, the correct answer is option E.
