Solution

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.
