NATURAL PROCESS SAMPLE
Life Cycle of a Frog
The flow chart illustrates the development of a frog from egg during its life
cycle.
Overall, it is clear that
there are six distinct stages
illustrated in the process,
commencing with
producing eggs in the water
and ending with
the
development of a mature frog.
The first stage is when
the eggs, shown as frogspawn, float on the surface of
the lake.
The next step after this is
the emergence of the small tadpole
after
the frogspawn hatches.
At this point in the cycle
, the small tadpole has a
small body with a long tail.
Over time
, the tadpole grows and its body
becomes bigger
while
the tail becomes longer.
At the same time
, the legs
begin to form
so as to
prepare the tadpole’s future life on land.
Eventually
,
the tadpole starts to grow into a young frog with a wider mouth, a shorter tail
and larger legs
although
it continues to live in the water.
Gradually
, the frog
becomes mature, ready to leave the water and moves onto the land.
When
being on land, it starts to breathe air and loses the tail.
The final stage of the
cycle is when
the adult frog finds a mate
in order to
lay eggs.
Having
completed all these steps
, the lifecycle will then begin again.
