उत्तर
Amphibians
Explanation:
About 32 percent of amphibian species are at risk due to factors like habitat loss, pollution, and environmental changes. This vulnerability is higher compared to insects, reptiles, and mammals. The decline is largely caused by habitat destruction, environmental sensitivity, and other human-induced factors, making amphibians one of the most threatened groups in biodiversity conservation efforts.
