students today we are Studying chapter
organisms and environment part 1 in that
we are studying topic ecosystem pattern
when I say ecosystem pattern EKOS means
the environment around us and pattern
means changes for example if you visit a
forest I don't want to see same kind of
freezing forest no different kind of
freeze in different forest that is
ecosystem pattern.
Ecosystem pattern when I say eco it
means ecology and pattern is nothing but
changes the biotech as well as oh by the
components of an ecosystem may vary from
location and time and this variation
allows in the formation of different
ecosystem pattern this is a definition
of ecosystem pattern for example if you
visit a garden you don't want to see
small trees which are roses shrubs
you're going to see victories like
banyan tree or chico tree even will see
grasses which are present on the ground
you will see a lot of birds which could
be sparrow or strange or in your kind of
birds if you visit Australia or some
other place in the country so different
places around the globe will have
different ecosystem when I say but take
components
it means the living components and when
I say our biotic component it means the
long living components for example if I
see that ecosystem pattern on earth it
compromises of animals plants trees
human beings which are living or biotic
components Venice mountains ponds lakes
atmosphere hydrosphere lithosphere all
this are by the company's well as
nonliving components when there's biotic
components and robotic components come
together in different proportion and
different location at different point of
time it forms ecosystem pattern and no
two places can have same ecosystem
pattern until unless it is forced on for
example if you plan in your house to
plant 100 trees 100 plants of to see
then your house can have same ecosystem
pattern of to see but in nature same
ecosystem pattern is not enough
especially in forest or in gardens it is
seen that once you have variation in
trees plants or animals every organism
supports the another organism for
example if you plant a great tree beside
a mango tree the graves will climb on
the mango tree and the produce grapes
basically climbers so both your mango
tree and your grapes leaves in ecology
or in harmony the main primary factor of
ecosystem is that every ecosystem
pattern should support each other and
should be able to survive from time to
time
the definition of ecosystem battle is
the biotech that is living and obey the
nonliving factors of an ecosystem may be
a liquid location and panel and this
variations allow formation of different
Spade PL pattern when Isis fatal pattern
it means different varieties of tree if
there are only mangroves in a particular
forest or a beachside
then that is one type of spatial
organization that is similar type of
spatial organization
special organization can be of two types
one is donation and the another one is
stratification Paracels donation as you
can see in the diagram below there are
two plans which are of similar origin
which are of similar kind and they are
of same length that is called as
zonation same plant and of same length
approximately similar for example a
forest full of mangoes that is zonation
type of spatial organization the next
type of spatial organization is
stratification stratification means at
different levels in stratification you
can see different kinds of tree which
have different lengths or different or
ecology even they are of different
origin a forest in which there are
different kinds of field mangos shrubs
grasses banana chiku basically a mixed
forest so stratification has different
lengths of plants with different origin
plants students in this part of the
chapter we have studied how diversified
an ecosystem pattern could be it could
be of zonation type or of stratification
type I hope you are clear with the
concept of zonation and stratification
which is based on ecosystem pattern
thank you
