Based on the reported estimates of biodiversity in India, select the correct option that represents the decreasing order of the total number of species reported in these taxa.

Correct option is B

The biodiversity estimates for various taxa in India show that the order of species diversity is reported as follows:

(b) Insects > Angiosperms > Algae > Fishes > Birds > Mammals

Information Booster:

1. Insects are the most species-rich group in India, with an estimated 80,000 to 100,000 species. They are the largest group of animals and occupy nearly every ecosystem in India.

2. Angiosperms (flowering plants) come next with approximately 20,000 species in India. Though plants are highly diverse, Insects outnumber them in terms of species count.

3. Algae, which include both freshwater and marine species, have significant biodiversity but are not as rich as Insects or Angiosperms.

4. Fishes have about 2,500 species in India, with more species in freshwater systems, but still fewer compared to Insects and Angiosperms.

5. Birds are also highly diverse with over 1,300 species but come after Fishes in the overall hierarchy of species richness.

6. Mammals have the fewest species in comparison, with around 400 species in India.
