Answer -
There is a huge difference in the percentage of species diversity of plants (22%) and the species diversity of animals (72%). It is due to the following reasons:
• Adaptation of animals to changing environments for survival. For instance – animals and insects have grown to develop a complex nervous system for coordinated and controlled body movements. Also, insects have grown to be versatile and developed a potential to survive in different habitats in comparison to other life forms as they possess repeated body segments with external cuticles and paired appendages
• Plants are immobile while animals can move around. Hence, animals have achieved more diversity as they have moved and adapted to different habitats.
