L14 Microbes as decomposers - Micro Organisms, Science, Class 8 Video

hello friends this video on
microorganisms friend and foe part 14 is
brought to you by exam feel calm no more
fear from exam so now let us look at how
microbes are so good as decomposers so
just how I touched a positive composure
saying that they help to decompose the
dead and decaying matter so let us see
how exactly they do it then which are
the microbes which act as decomposers so
what is the composition composition
means formation now we often say right
this is composed of this sentence that
means this is made up of so composition
is always about making something
decomposition is just the opposite of
that that means breaking something so
this is the process in which complex
organic matter and broken down into
simpler forms so what does this complex
organic matter the complex organic
matter is nothing but the dead remains
of plants and animals so that is the
Papago they are all organic they are
carbon containing substances so that
complex organic matter will be broken
down into simpler forms simpler forms
could be inorganic materials may be
nitrogen phosphorus which act as
nutrients for the plants so it could be
inorganic nutrients or it could be
inorganic substances like nitrogen gas
which is reduced back to that whole
sphere so basically complex organic
matter has converted into simple
inorganic substances so the organisms
which help in this process of breakdown
they are quite decomposers so the names
have to match organisms which has been
decomposition has to be decomposers so
bacteria and fungi are the important big
composers so his over these two classes
of microorganisms they act as
decomposers so in a way we can say that
these decomposers help us to clean the
earth had the desired things decomposers
not been there in that case the dead
plants and dead animals would have just
accumulated on
because there would have been nothing
else who could have broken down the
organic matter into these inorganic
substances and this email there if
substances eventually get utilized by
the plants so they help environment to
get rid of dead and decaying matter as I
said just now otherwise half or more
than half of the earth would have been
done just by their bodies enrich the
soil quality because it converts it into
inorganic substances like nitrogen which
definitely improves the quality of the
soil and also its fertility so the
process is really simple complex things
are being broken down into simple forms
so the picture itself speaks for itself
you have something very populous made up
of a lot of things you break it down
into simple forms and these simple forms
can then be utilized by some other other
organism existing on the earth so it is
not causing any sort of environmental
pollution in any way and who helps us in
doing that bacteria and fungi so another
way they are again the microbes so see
by now we have actually seen microbes
doing so many good things for us for our
environment so we cannot say that
microbes can only cause disease and only
cause harm to us so there are so many
friendly microbes as well thank you
