N FROGS METAMORPHOSIS IS BROUGHT BY THYROXINE HORMONE.THE PRODUCTION OF THYROXINE HORMONE REQUIRED THE PRESENCE OF IODINE IN WATER.SO IF THE WATER IS DEFFICIENT IN IODINE,THE TADPOLES LIVING THERE CANNOT PRODUCE SUFFICIENT THYROXINE & CANNOT BECOME ADULT FROG.

Tadpoles growing in Iodine deficient water fail to grow into frogs, as the throxine production is low.
Explanation:
Usually the growth and metamorphosis in frogs is regulated by thyroxine gland. This hormone is secreted from thyroid gland.
The addition of a trace of the thyroxine or the iodine in the water having tadpoles will rush or speed up their metamorphosis.
It is known that iodine is the major source required for thyroxine production.
This is the reason why retarded growth is seen in tadpoles living in iodine deficient water.
