They don't, they lay eggs, though there may be one or two species that carry their eggs in their mouths, or in pouches on their backs for protection until they hatch. One exception are species from the genus Nectophrynoides; these are live-bearers.
Frogs are sensitive to aquatic environmental pollution and it is mainly for this reason that their demise has attracted considerable concern. Frogs lay naked, unprotected eggs in fresh water. The eggs and tadpoles are therefore exposed to aquatic pollutants which either interferes with growth processes (thus causing abnormalities), or are so toxic that they will kill them.
The trigger for awareness was the extinction of the Gastric Brooding Frog, Rheobatrachus silus in southeast Queensland, Australia. In 1974 it was reported to be unique in the animal kingdom in swallowing its eggs, incubating its young in its stomach, and giving birth to baby frogs through its mouth. This news attracted worldwide attention, but one winter the total population disappeared. It has not been seen for 25 years!

None. Frogs are amphibians and all amphibians start off as eggs, then tadpoles, and then eventually frogs.
None. Frogs don't give birth, they lay eggs.
Frogs hatched from eggs. Eggs hatch into fishlike young called tadpoles which grow and eventually undergo metamorphosis, a change in body form, to become adults. But some frogs do not have a tadpole stage, instead, tiny froglets hatch directly from the eggs.
no only samon do... aquarium fish ofcourse do not. they only live as long as their lifespan
Several animals evolve after birth including frogs and toads. These animals are born as tadpoles and become frogs after birth. Many insects like butterflies also evolve after birth.
No, frogs cannot give birth anywhere. They lay eggs.
No.
Frogs do not give birth. They lay eggs.
frogs give brirth in slow moving water near shore under rocks,tree bark and fallen trees. They give birth in march to may.
Give live birth.
Frogs and Toads lay eggs the one exception is the Nectophrynoides it has been known to give live birth.
Frogs lay eggs rather than giving birth to live young. They lay sometimes hundreds of them and some eventually hatch into tadpoles and become frogs themselves.

Frogs lay a lot of eggs because a lot of animals eat tadpoles and small frogs including other frogs.

its more easy to give birth in water
Most, but not all, species of frogs are oviparous; that is, they lay eggs in order to reproduce. Some species of frogs give birth to live young, such as members of the African genus Nectophrynoides and other species found in the Andes and Central America.
