Reptiles and amphibians play a significant role in the ecosystem. Amphibians are one of the primary connections in many ecosystem food webs. In temperate and tropical regions, amphibians can exceed all other terrestrial vertebrates such as birds, mammals, and reptiles. Amphibians are important predators of invertebrate. Frogs, for example, control the insect population, and they are a food source for many larger animals.
Amphibians matter because a significant decline in amphibian diversity can cause a major reduction in the health and sustainability of ecosystems, and this can lead to a deterioration of the quality of human life. Amphibians play an integral role in pest control, water filtration, and medical research.
