mmmmmm
Still, the ___________
coast
&
especially the ___________ continental shelf have lots of ocean life!
Slide10Especially during UPWELLING! LOTS of GOOEY EDIBLE MUCK…
mmmmmm
Still, the INTERTIDAL
coast
&
especially the NERITIC continental shelf have lots of ocean life!
Slide11The intertidal and neritic zones have lots of life because
of the
_ _ _ !
The _ _ _ kicks off
______________!
Slide12The intertidal and
neritic
zones have lots of life because
of the SUN!
The sun kicks off PHOTOSYNTHESIS!
Slide13The INTERTIDAL and NERITIC zones still have plenty of life
of their own
because
of the SUN!
The sun kicks off PHOTOSYNTHESIS!
Slide14With PHOTOSYNTHESIS,
most producers (kelp,
phytoplankton like _____
)
can
make their OWN _____ food!
Slide15With PHOTOSYNTHESIS,
most producers (kelp,
phytoplankton like algae
)
can

Slide19But there is no _____ in the
deep zone
(aka benthic zone).
Slide20But there is
NO SUN
in the
deep zone
(aka BENTHIC).
Slide21WHAT IS THE energy source OF BENTHIC FOOD WEBS?
Without the SUN
,
Slide22Got any ideas?
It can’t get it’s energy from the sun!

DROTHERMAL VENTS spew all sorts of
gases
for things to live on!
Chemosynthetic bacteria
use inorganic molecules as a source of energy including ____________ (NH3) , ___________(S) and __________ ____________ ( H2S ).Like their sun-loving photosynthesizers,
chemosynthesizers
are _____________ because they produce their own food.
____________ ________are
located very deep into the ocean where sunlight is unable to penetrate; therefore, the organisms that live at
____________ ______
obtain their energy from the
__________
ejected out from the ocean crust
.
Since the energy from the
____
cannot be
used
at such depths, the
_______ ________ absorbs ___________ _________
(H
2
S) from
the vent and provides it to the bacteria.
So, these two living things have a ___________
MUTUALISTIC
relationship.
Slide28http://hubpages.com/education/What-are-Chemosynthetic-Bacteria
DROTHERMAL VENTS spew all sorts of
gases
for things to live on!
Chemosynthetic bacteria
use inorganic molecules as a source of energy including AMMONIA (NH3) , SULFUR (S) and HYDROGEN SULFIDE (
H
2
S
).
Like their sun-loving
photosynthesizers
,
chemosynthesizers
are
PRODUCERS
because they produce their own food.
HYDROTHERMAL VENTS
are
located very deep into the ocean where sunlight is unable to penetrate; therefore, the organisms that live at
HYDROTHERMAL VENTS
obtain
their energy from the
CHEMICALS
ejected out from the ocean crust
.
Since the energy from the
SUN
cannot be
used
at such depths, the
TUBE WORMS
absorb
HYDROGEN SULFIDE
(H
2
S) from
the vent and provides it to the bacteria.
So, these two living things have a
SYMBIOTIC
MUTUALISITIC
relationship because they help each other

Methane Ice Worms
Hesiocaeca
methanicola(larger view)A team of university scientists using a mini research submarine on a NOAA-funded research cruise has discovered, photographed, and sampled what appears to be a new species of centipede-like worms living on and within mounds of methane ice on the floor of the Gulf of Mexico, about 150 miles south of New Orleans.Although scientists had hypothesized that bacteria might colonize methane ice mounds, called gas hydrates, this is the first time animals have been found living in the mounds.
The discovery of dense colonies of these one-to-two-inch-long, flat, pinkish worms burrowing into a mushroom-shaped mound of methane seeping up from the sea floor raises speculation that the worms may be a new species with a pervasive and as yet unknown influence on these energy-rich gas deposits.
