Answer:
Amphibians are more vulnerable to
extinction
(i) Habitat Modification or
Destruction Amphibians generally need aquatic and terrestrial habitats to
survive; threats to either habitat can affect populations. Hence, amphibians
may be-more vulnerable to habitat modification than organisms that require only
one habitat type.
(ii) Habitat Fragmentation This
means isolation of a few areas by habitat modification. Small populations that
survive within such fragments are often susceptible to inbreeding, genetic
drift or extinction due to small fluctuations in the environment.
(iii) Large Scale Climate
Changes These changes can further modify aquatic habitats, preventing
amphibians from spawning.
