are studying chapter organisms and
environment part so in that we are
studying topic decomposition in eco
system whenever somebody dies the dead
body comes to soil and inside soil
are microorganisms which basically
decompose and they're not one type of 
microorganism there are numerous present
today we'll be studying about them.
Decomposition decomposes are organisms
that break down complex organic matter
which is present inside soil or water
into inorganic or organic substances
like carbon dioxide nutrients and
substances whenever somebody dies the
body or the dead body is basically
burned and when you burn the dead body
whatever goes back to the soil that I
decomposed is present or small
microorganisms present a type of
scavengers which basically take out the
last nutrients present inside that dead
body and convert the dead body nutrients
back to soil so your bones from the soil
and you go back to soil there are four
steps on which decomposers work and the
steps are fragmentation leaching
catabolism and unification when I say
fragmentation fragments fragments are
nothing but pieces whenever somebody is
burnt or you put something to soil you
put a big chunk or a big piece obviously
so now how this decomposition process
works the big pieces are broken down
into smaller pieces and this process is
called as fragmentation or breaking in
different small pieces the next step is
leaching lynching is nothing but
converting water-soluble products or
products which are mixable in soil into
products which can completely and fully
get converted into soil that particles
that is leaching the third step is
catabolism catabolism and anabolism we
have studied catabolism is nothing but
converting those products which are
fragmented into particles which can be
used by soil and from soil it can be
used by us human beings for animals or
folk rock group as we all know crops for
the Guru bleep carbon dioxide sulfur
nitrogen phosphorus and during the
professor of catabolism it is taking
care that all these products are formed
from that dead body and all this process
ensures that the last process is
unification now human ocation
there are two steps in formation of
humors and for
new transfers organic substance humans
is nothing but soya like substance ashes
which are formed with the dead bodies
burned are a form of humans which get
mixed into the soil which is brownish in
color well s once ash is completely
mixed into the soil what you get is
nutrients or organic compounds and this
organic compounds are neutrals could be
carbon nitrogen oxygen sulfur various
other calcium magnesium molybdenum all
those things which act as phytonutrients
or micronutrients or macro nutrients for
the plant go so this is where decomposes
help mankind or ecosystem in a better
way by giving back to the ecosystem of
the Sun which will help every other
species whether it is biotech or about
it in their growth
decompositional ecosystem for the
decomposes involved in ecosystem
decomposes break down complex organic
substance or compound organic substances
into organic or inorganic molecules
basically into simpler substances like
carbon dioxide nutrients like carbon
nitrogen sulfur etc the steps in
decomposition of physical for
fragmentation leaching catabolism and
unification
the four steps or decomposition app
fragmentation that is breaking down of
larger molecules or complex molecules
into simpler molecules fragmentation is
nothing but breaking down in pieces the
next step is leaching mixing of water
soluble products into soil catabolism
catabolism is nothing but a process that
is carried out by bacteria present
inside soil it was simpler compounds on
nutrients you can see and the last step
human this is nothing but formation of
nutrients plus humors humors is soil a
particle
the basic picture of decomposition is
that auditor is for a dead organism or a
dead body's present which undergoes
decomposition in soil after certain
period of time after the four steps of
deep composition the last step is
basically human fication the formation
of humors or soil acts substances and
mineralization that is formation of
nutrients and organic matter the
formation of phosphorus nitrogen sulphur
all these things which are given to the
soil for the growth of plants students
in this part of the chapter we have
started about decomposition the various
steps of decomposition and how humans
only truths are formed inside soil which
makes oils more viable more rich in
compounds
I hope the topic of decomposition in
ecosystem is clear to all of you thank
you
