What could be the possible explanation for greater vulnerability of amphibians to extinctions as compared to other animal groups ?

Explanation

### Step-by-Step Solution:

1. **Habitat Loss**: One of the primary reasons for the greater vulnerability of amphibians to extinction is habitat loss. Amphibians require both aquatic and terrestrial habitats for their life cycle. The destruction of wetlands, ponds, and forests due to urbanization, agriculture, and industrial activities significantly impacts their populations.

2. **Complex Reproductive Needs**: Amphibians have complex reproductive requirements, often needing specific environmental conditions for breeding. Many species lay eggs in water, and the presence of suitable aquatic habitats is crucial for their reproductive success. Changes in the environment can disrupt these conditions, leading to decreased reproduction rates.

3. **Pollution**: Amphibians are particularly sensitive to pollution, especially water pollution. The introduction of harmful chemicals, such as pesticides and heavy metals, into their aquatic habitats can lead to toxic effects, affecting their health and survival. Their permeable skin makes them more susceptible to pollutants compared to other animal groups.
