Give the correct descending order of the following vertebrate groups with reference to their global species diversity, as represented in standard ecological estimates. (a) Birds (b) Mammals (c) Reptiles (d) Amphibians (e) Fishes Choose the correct answer from the options given below :

Step-by-step solution

According to global species diversity estimates, the approximate number of species in different vertebrate groups is as follows: Fishes: 32,000 Birds: 10,000 Reptiles: 9,000 Amphibians: 7,000 Mammals: 5,500 Arranging them in descending order of species diversity, we get: Fishes > Birds > Reptiles > Amphibians > Mammals This corresponds to (e) > (a) > (c) > (d) > (b). Answer: (e) > (a) > (c) > (d) > (b)
