Amphibians

The difference between frogs and toads are that
Frogs-
Their skin is moist and smooth
They are a symbol of fertility
They can jump up to 36 times our size

Toads-
Their skin is dry and rough
They have poison glands behind each of their eyes
They walk instead of hop
Associated with witch craft

B: indicators of a healthy ecosystem
Toads and frogs are indicators of a healthy ecosystem because it means that there is a body of water some where
Close.
-whenever frogs are sick or disappearing it means there's something wrong with the ecosystem
-frogs alert scientist by the quality of their skin and health if there is pollution in the air or in the water

C: frog decrease
The frog and toad population is decreasing because of habitat loss and fragmentation, chemical pollution, increased ultraviolet radiation, acid precipitation, commercial harvest. Most of the problems can be directed towards human and the environment
