L2 : Why do we need food - Components of Food , Science, Class 6 Video Lecture

hello friends this video on components
of food part 2 is brought to you by exam
for calm novo to your prom exam fish etc
but the question is there is so much of
variety in the food but why do we need
food so this is something which we
already answered in the previous lesson
because food is something that gives us
energy right so what we learned is food
gives us energy to do various activities
whether you look at this lady who is
performing yoga so when you perform yoga
or when you try to do exercise have you
noticed that if you exercise
continuously for a half an hour on one
hand what happens at at the end of one
arm you tend to these diode why because
when you are doing the exercise or when
you are doing yoga a lot of energy is
being spent in doing that so as a result
what happens you tend to you are losing
energy
gradually so think of doing any kind of
activity whether you see this man who is
sucking down a tree though cutting down
a tree is not a good thing to do but
when he is doing this job he is doing
some work so some energy is being spent
from this body therefore after some time
again he also gets tired so whether you
job or even when you think you are
actually not doing any physical work but
still some energy is being spent by your
body so your body needs energy to think
so have you ever seen that when you are
very hungry you haven't eaten anything
since morning and then you are asked to
solve a problem in mathematics so have
you noticed that you don't feel like
doing it because you know you are
feeling hungry so your entire
concentration is towards your hunger so
you are not able to think you are not
able to apply your brain so that's
because even your brain works only when
there is energy in your body so it means
energy to work even when we sleep our
body needs energy that's because when we
are sleeping we are not doing any work
but the organs inside our body they are
still working so even when we sleep our
heart beats even when we see the blood
circulate
throughout our bodies even when we sleep
we breathe in breathe out
so all these activities are still taking
place inside our bodies and energy is
needed for these activities also to
perform and very good we need energy
from where are we going to get that
energy so that can energy comes inside
our body through food
so when study we need energy so in that
case we definitely need a lot of energy
so here we saw that to do any kind of
activity whether it is on physical
activity or mental activity you would
need some energy inside your body and
you get that energy through the food
which we eat so food is extremely
essential that is why if you stop eating
food for some time your body doesn't
have energy so gradually you will not be
able to perform any of the physical or
mental activities and finally the
processes which are taking things inside
your body that might also stop because
they also need energy to do their job so
that is why it is very important to eat
proper food so now the next question is
