what are abiotic factors?
Non-living
factors
abiotic factors that may affect an ecosystem
light
intensity
temperature
moisture
soil
pH
and
mineral content
O2
level
CO2
level
wind
intensity
and
direction
why might light intensity affect an ecosystem?
different
species
of plants may have different
optimum light intensities
for
growth
why does temperature affect an ecosystem?
different
species
of
plants
and
animals
may have different
optimum
temperatures for
growth
and
survival
how does soil pH affect an ecosystem?
certain plants may
grow
better
in either
alkaline
or
acidic
soil
soil pH may affect the
appearance
of the plant
how does moisture level affect an ecosystem
many
plants
can’t
survive
in
waterlogged
soil as their
roots
can’t
respire
certain plants are
adapted
to
high
moisture levels
how does wind intensity affect an ecosystem?
plant
seeds
are more likely to
germinate
in locations with
lower
WI which may also
attract
animals that
depend
on the plant to live
nearby
how does soil mineral content affect an ecosystem?
most
plants
require a
high level
of
soil minerals
to
grow
well
example of a type of plants that have adapted to low soil mineral content
carnivorous
plants catch
insects
to compensate for the
low
level of
soil mineral content
how does carbon dioxide concentration affect an ecosystem?
higher
CO2 concentration leads to
more
plant growth
how does oxygen concentration affect an ecosystem?
aquatic animals
cannot
survive
in areas with
low
oxygen concentration
