The diversity of animals is much more than the diversity of plants because the animals are mobile and move from one place to another. Thus they moved to different habitats and achieved more diversity. The animals have adapted themselves to the changing enviroment by developing various features like  complex nervous system, protective external layer or cuticles for better survival as compared to plants.
