Answer 1
Natural causes such as rivalry, predation, mating and disease, as well as human-induced pressures such as habitat destruction, environmental pollution, endangered plants and climate change, are all contributing to amphibian decreases. Amphibians endure a double whammy due to their permeable skin and susceptibility to both aquatic and terrestrial challenges. As a result, mammals, fisheries and wildlife have not suffered as severe population declines as amphibians — at least not yet.
As mentioned by da Costa Araujo et al., diseases caused by pathogens can result in developmental failures, which can lead to reproduction failures. Parasites, for example, may induce nutritional losses, which might lead to developmental delays or reproductive problems, but this potential has not been thoroughly explored in the science. Deformities caused by infections, in addition to affecting growth, will also have an impact on reproduction. Insects that induce limb malformations.
Answer 2
In order to stop the populations of the amphibians from declining, we should consume organic foods. We may immediately contribute to reduce the amount of chemical contamination, which influences many amphibian species by limiting pesticide and fertilizer use. We should avoid releasing estrogens from the...
