etc are hashed from the eggs the food
for the baby he is contained in the egg
itself first we will see that how birds
reproduction all the birds are egli
animals before laying eggs the birds
Magnus to keep their egg safe and warm
in the process of hatching the animal
sorry the female bud sits on the eggs to
keep them warm and it has developing
baby called the embryo let's sister turf
an egg this is the outer layer of an egg
is called shell it protects the egg and
in the scent of egg there is a yellow
part that is York in the York the embryo
has so this is the growing baby and this
is admin it has water 2.1 so yolk has
developing baby called embryo now we
will see that reproduction in frogs a
frog is a cold-blooded animals it lays
all the egg in water frogs eggs are also
card spawn after a few days frogs eggs
hatch and too little back tadpoles and
they
they look like a fish after that baby
frogs and Iron Throne so the duct add /
change into adult frog after a few days
now reproduction in insects all insects
download from eggs some insects such as
grasshoppers and cockroaches pass
through three stages in their life cycle
we take the example of poor watch then
the eggs of a garage hatch the baby
cockroach come out that is called nymph
and they look like a date approaches
they shed their skin is called Moulton
after a few days so after survival
malting leave become adult cockroach now
reproduction in fishes the fish lives
thousands of eggs in water fish eggs are
a spawn the young baby fish hatch
and grow you fry and fry it grows to be
an adult fish many egg and baby fry is
written by big fishes and many eggs are
alt do to foster currents now reptiles
whereas are those animals that all on
the ground like Liz are snakes turtles
electrum lizard and snakes leave their
eggs on the ground but many of them iden
by other animals
