Forests
are
among
the
most
complex
ecosystems
in
the
world,
and
they
exhibit
extensive
vertical
stratification.
Conifer
forests
have
the
simplest
structure:
a
tree
layer
rising
to
about
98
feet
(30
metres),
a
shrub
layer
that
is
spotty
or
even
absent,and
a
ground
layer
covered
with
lichens,
mosses,
and
liverworts.
Deciduous
forests
are
more
complex;
the
tree
canopy
is
divided
into
an
upper
and
lower
storey,
while
rainforest
canopies
are
divided
into
at
least
three
strata.
The
forest
floor
in
both
of
these
forests
consists
of
a
layer
of
organic
matter
overlying
mineral
soil.
The
humus
layer
of
tropical
soils
is
affected
by
the
high
levels
of
heat
and
humidity,
which
quickly
decompose
whatever
organic
matter
exists.
Fungi
on
the
soil
surface
play
an
important
role
in
the
availability
and
distribution
of
nutrients,
particularly
in
the
northern
coniferous
forests.
Some
species
of
fungi
live
in
partnership
with
the
tree
roots,
while
others
are
parasitically
destructive.

soil
erosion
d)

in
the
forest
are
not
dependent
upon
each
other.

of
these
26.5.
