Their body is streamlined. This shape provides little resistance during flight.
Forelimbs are modified into wings and hindlimbs are shifted forward to balance their body weight.
Flight muscles are present to provide additional strength during the flight.
All birds have a light body as the bones are hollow and have air cavities. Their bones do not have bone marrow.
Hello students, this is Neha and I
welcome you to
online homework solving session today we
will look at the following
the question says to describe the aerial
Adapted in words
in this question, we have to tell
what is the adaptation in birds?
which makes them fly that is aerial
so the aerial adaptation in word look at
the structure of the board here
When I look at the structure of the bird
Here I can see
that the body is like a boat
here when I look at the bird structure
the body is a boat or a spindle shape
Okay, so here I can say the body is
boat or spindle shape
and as the body is brought or the
spindle shape I can say
actually the body is streamlined
now how does this help streamlined
as it provides little
resistance during flight
that is when they fly they face
very little resistance, this is the first
the part looks at the second part here
in this, we can see wings so there is no
of four limbs so the four limbs here
are modified into wings so the four
are modified into wings
and the hitch limbs
the hint limbs
have shifted a bit forward so that proper
balance can be maintained
of their body weight so these are the
one more when I look into this
we have flight muscles so that
strength can be provided during the
during the flight that is when they fly
additional strength can be provided
and next when I look at the bones see
even the birds that fly it is very important.
that the bones
are of less weight so they have
pneumatic bones now what is
pneumatic bones this
all birds have a light body
as they both are hollow
and they have an air cavity in it
and these bones do not have their own narrow
so this is how we approach this question.
