Short Answer TypeThe 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?
(i) Habitat loss and fragmentation:Loss of habitats due to natural calamities or human activities lead to loss of species diversity.
(ii) Over-exploitation: Due to over-hunting and over-exploitation of various plants and animals by humans, many species have become endangered or extinct .
(iii) Alien species Invasions: Accidental or intentional introduction of non-native species into a habitat lead to the declination or extinction of indigenous species.
(iv) Co−extinction: In a native habitat, one species is connected to the other in an intricate network, thus the extinction of one species causes the extinction of other species.
