Question

what are the reasons that you can think for the arthopods to constitute the largest group of animal kingdom

Answer 1

Hi there!
The reason for arthropds to be the largest phylum is simply that there are about 9 lakh species in this phylum. Also over two thirds(about 60 to 70 %) of all the named species on earth are arthropds.

Answer 2

Hello there ,

The phylum, Arthropoda, consists of more than two-thirds of the animal species on earth. The reasons for the success of arthropods are as follows.

>>Jointed legs that allow more mobility on land

>>Hard exoskeleton made of chitin that protects the body

>>The hard exoskeleton also reduces water loss from the body of arthropods making them more adapted to terrestrial conditions.
