Feeding in frogs

 They feed on small insects and worms

 They use their long sticky tongues to trap their prey.

Reproduction in amphibians

 The tadpoles undergo several changes to full develop into an

adult.

 The male and female mate.

 This takes about three months.

 The female lays eggs and the male sheds sperms over them

to fertilize them (external fertilization).

 The eggs develop and after about two weeks hatch into tad-

poles.
