Question

Which is the cause of the decline of amphibians in nature​

Answer 1

There are numerous known factors that contribute to amphibian declines—habitat destruction, pollution, and newly introduced or invasive species, to name just three1. Many of the causes of amphibian declines are well understood, and appear to affect other groups of organisms as well as amphibians2. These causes include habitat modification and fragmentation, introduced predators or competitors, introduced species, pollution, pesticide use, or over-harvesting23.
