amphibians are known as biological indicators. When the environment gets polluted from pesticides or ozone depletion they are the first to be affected. Since most amphibians breathre through their skin and absorb water that way the amphibians can die from the pesticides that are put in water. Sometimes they can even cause birth defects for example a five-legged frog might occur, because of this their population is decreasing. When people discover what is happening to them, we all know that this is what we are doing to them. We made the ozone layer thinner, we put pesticides in water.
Because when they start dying that means that something is wrong just like any kind of animal knows when danger is near
Becuase they breathe through theis skin, the skin is very permeable. This makes amphibians very vulnerable for waterpollution.
Because unhealthy amphibians can be an early sign of changes in an ecosystem.
Not nearly as much dependence on reptiles as amphibians. Reptiles can endure many more environmental assaults than the amphibian that preforms a significant amount of it's gas exchange through it's skin.
biological indicator of air pollution is lichene. it is a best example of air pollution indicator.
Biological indicators are species used to monitor the health of an environment or ecosystem.

The natural indicators are blackberry and many other bright-coloured flowers make good natural indicators
Some theorists are saying pigeons. You know like city pigeons? Well That is what they are saying
DNA is a biological phenomenon visible through generations of reproduction. Diamonds have no generational cycle. Some diamonds, do, however, contain trace minerals that can be good indicators of their place of origin and discovery on the planet.
Pictures that show amphibians in their natural habitat or pictures capturing amphibians in rare moments that are almost impossible to see. That depends on what you view as a good picture.
yes because they can withstand heat and cold but not smoke or fumes and this is how we know they are good indicators of air quality
