Question

The species diversity of plants (22 per cent) is much less than that of animals (72 per cent). What could be the explanations to how animals achieved greater diversification?

Answer 1

Ans. The species diversity of plants is much less than that of animals which is about 72 percent. This large difference in diversity is because animals have adapted themselves to ensure their survival in the ever changing environment. On the contrary plants have not adapted themselves to such circumstances. Insects and other animals have well complexed nervous system to control and cordinate their body structure. The body segments with paired appendages and external cuticles give the insects the ability to survive in various habitats.
