How deep can we go? Part 2

Let’s review…

The deep ocean zone (BENTHIC zone) is the LARGEST sized ocean ______ by far! Because of crushing pressure, darkness, and its huge size, most of it is unexplored!

The deep ocean zone (BENTHIC zone) is the LARGEST sized ocean ECOSYSTEM by far! Because of crushing pressure, darkness, and its huge size, most of it is unexplored!

Still, the ______ coast & especially the ______ continental shelf have lots of ocean life! Especially during _______! LOTS of GOOEY EDIBLE MUCK…mmmmmm

Still, the INTERTIDAL coast & especially the NERITIC continental shelf have lots of ocean life! Especially during UPWELLING! LOTS of GOOEY EDIBLE MUCK…mmmmmm

The intertidal and neritic zones have lots of life because of the _ _ _ ! The _ _ _ kicks off _______!

The intertidal and neritic zones have lots of life because of the SUN! The sun kicks off PHOTOSYNTHESIS!

The INTERTIDAL and NERITIC zones still have plenty of life of their own because of the SUN! The sun kicks off PHOTOSYNTHESIS!

With PHOTOSYNTHESIS, most producers (kelp, phytoplankton like _____) can make their OWN _____ food!

With PHOTOSYNTHESIS, most producers (kelp, phytoplankton like algae) can make their OWN sugar food!

Sometimes _____ can run AMOK! Usually because of run-off fertilizers from land _____.

Sometimes algae can run AMOK! Usually because of run-off fertilizers from land farms. eeeee. EUTROPHICATION

Sometimes algae can run AMOK! Usually because of run-off fertilizers from land farms. eeeee. EUTROPHICATION

But there is no _____ in the deep zone (aka benthic zone).

But there is NO SUN in the deep zone (aka BENTHIC).

Without the SUN, WHAT IS THE ENERGY SOURCE OF BENTHIC FOOD WEBS?

Got any ideas? It can’t get it’s energy from the sun!

How does life start in the ABYSS? CHEMICAL ENERGY ! (not solar energy) http: //hubpages. com/education/What-are. Chemosynthetic-Bacteria

How does life start in the ABYSS? CHEMICAL ENERGY ! (not solar energy) HYDROTHERMAL VENTS spew H 2 S for CHEMOSYNTHESIS!

PHOTOSYNTHESIS…

http: //hubpages. com/education/What-are. Chemosynthetic-Bacteria DROTHERMAL VENTS spew all sorts of gases for things to live on! 1. 2. 3. 4. Chemosynthetic bacteria use inorganic molecules as a source of energy including ______ (NH 3) , ______(S) and ____________ ( H 2 S ). 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.

http: //hubpages. com/education/What-are. Chemosynthetic-Bacteria DROTHERMAL VENTS spew all sorts of gases for things to live on! 1. 2. 3. 4. Chemosynthetic bacteria use inorganic molecules as a source of energy including AMMONIA (NH 3) , 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

Life exists even in the ABYSS! HOW? CHEMICAL ENERGY ! (not solar energy) hydrothermal vents, submarine hot springs, and methane seeps; chemosynthetic organisms; dead stuff.

PRESS RELEASE Date Released: Tuesday, July 29, 1997 Source: Pennsylvania State University 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.
