Review How
to
do
a
Lab-based
experiment
(Scientific
Experiment
Method)
-
ANS
-
IV/DV
-Control
Group
-Experimental
Group
-Lab
setting
-30
in
each
group
-Constants
-How
long
it
took
to
do
the
experiment
-Measurements
Ecosystem
-
ANS
living
organisms
and
the
physical
and
chemical
factors
which
influence
them
(abiotic
and
biotic
components)
Example:
A
rocky
shore
Habitat
-
ANS
the
place
where
organisms
live
Example:
the
area
surrounding
a
hydrothermal
vent
Population
-
ANS
consists
of
organisms
of
the
same
species,
usually
defined
as
living
in
the
same
area
Example:
a
population
of
ghost
crabs
Community
-
ANS
includes
all
the
different
species
living
in
a
habitat
at
the
same
time
Species
-
ANS
a
group
of
similar
organisms
that
can
interbreed
and
produce
fertile
offspring
The
Name
-
ANS
First
=
generic
name,
refers
to
the
genus
Second
=
specific
name,
refers
to
the
species
Biodiversity
-
ANS
takes
into
account
the
numbers
of
different
species
present
and
the
range
of
habitats
and
ecosystems
Example:
Coral
reefs
have
a
high
biodiversity
w/
many
different
species
present
Ecological
Niche
-
ANS
the
role
of
an
organism
within
an
ecosystem,
taking
into
account
its
relationships
with
other
organisms
Symbiosis
-
ANS
a
relationship
b/w
two
different
organisms,
where
both
derive
some
benefit
from
the
benefit
Example:
corals
and
zooxanthellae Parasitism
-
ANS
a
relationship
b/w
two
organisms
where
one,
the
parasite,
obtains
benefit
at
the
expense
of
the
other,
known
as
the
host,
which
is
usually
harmed
by
the
relationship
Example:
Tuna
and
Nematodes
Parasites
-
ANS
Split
into
two
groups:
Ectoparasites
and
Endoparasites
-Ectoparasites:
live
on
the
outside
of
their
host
(Fish
lice)
-Endoparasites:
live
inside
their
host
(Nematodes)
Producers
-
ANS
are
able
to
synthesize
organic
substances
from
simple
organic
compounds,
using
light
energy
from
the
sun,
in
the
process
of
photosynthesis
Example:
green
plants
and
algae
-They
provide
food
for
all
other
organisms
in
food
chains
and
food
webs
Consumer
-
ANS
an
organism
that
obtains
its
energy
requirements
by
feeding
on
other
organisms
Primary
Consumers
-
ANS
(Herbivores)
feed
on
plant
material
Secondary
Consumers
-
ANS
(Carnivores)
feed
on
herbivores
Food
Chain
-
ANS
shows
the
sequence
of
organisms
feeding
on
other
organisms
Chemosynthetic
Bacteria
-
ANS
able
to
produce
organic
substances
by
oxidising
hydrogen
sulphide
-found
in
hydrothermal
vents
Predator
-
ANS
an
animal
that
catches,
kills,
and
eats
another
animal
-usually
secondary
consumers
Trophic
Level
-
ANS
refers
to
the
'feeding
levels'
in
a
food
chain,
or
a
food
web
-Producers
occupy
the
first
trophic
level
-Primary
consumers
occupy
the
second
trophic
level
-Secondary
consumers
occupy
the
third
trophic
level
Producer
---->
Primary
consumer
---->
Secondary
consumer
What
do
the
arrows
mean???
-
ANS
The
arrows
represent
the
direction
in
which
energy
and
biomass
are
transferred
What
affects
the
numbers
of
predator
in
an
ecosystem?
-
ANS
-
The
availability
of
food
>
if
the
availability
of
food
increases,
the
numbers
of
predators
may
correspondingly
increase
(vice
versa)
Shoal
of
Fish
-
ANS
consists
of
large
numbers
of
fish
of
the
same
species
and
approximately
the
same
