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?
1. Fragmentation creates barriers that limit the potential of species to disperse and colonise new areas.
2. Species get divided into smaller populations and are unable to sustain.
3. Migratory birds lose their seasonal habitats.
4. It makes the species more vulnerable to predators as well as to wind and fire.
