Marine Life BiomeBy Lukas Struppe
Basic facts to know before you read this.
• The Marine Biome includes the ecosystems of all the bodies of SALT WATER NOT FRESH WATER.
• This biome includes the all the plants and animals living in salt water. In this report we will be focusing
specifically on the DEEP SEA BIOME!
CLICK TO ENTER THE
DEEP SEA
The Deep Sea How Deep?How Cold?
• The Deep Sea includes three zones:• Batheypelagic Zone (1000-4000m)• Abyssopelagic Zone (4000-6000m)• Hadopelagic Zone (6000-undiscovered)
• It ranges from about 1800 meters to 11,000 meters which is the deepest discovered so far.
• Average temperature at 4000 meters is 2 degrees Celcius
The Bathypelagic Zone• This zone is closest to the surface from the Deep
Sea Biome• The Biomass decreases (amount of
organisms/living things or dead organisms) • The prey feed on dead organisms that come from
higher up while the predators feed on the prey in their zone.
• Sunlight reaches only to 1000 meters so it is Pitch Black
• Some animals use bioluminescence to see and move around.
Yum!
Abyssopelagic Zone• No light is seen here• Anything living beyond this must be able to withstand
11,000 psi. (we would get crushed)• It is the largest living zone known to man• ≈115,000,000 square miles• The biomass is extremely high here because of all the
dead organisms that float down here. • There is little or no oxygen down here. • Predators usually use bioluminescence to catch other fish
or jellyfish• Most prey are camouflaged or transparent/translucent. • The jaws of the fish are large and low as to be able to
comb through the sand for food• Most fish are blind
Fun Fact: Abyssopelagic
Comes from the Greek meaning no bottom (but there is one)
The Hadalpelagic Zone
• Deepest known part of the ocean is the Marianas trench (11,021 meters)
• Mostly made up of deep trenches since most places are not deeper than 4,000 meters.
• 2% of the ocean is part of this zone• Very few organisms live down here
because of the extreme temperature and pressure.
Bathypelagic Food Webdead biomass debris
Large Crustaceans
Small Crustaceans and/or Copopods
Fish, squid, etc.
Abyssopelagic and Hadalpelagic Food Web
• Sadly there is no food web on these zones since so little is known.
• There is A basic food web though

***Also Shows the flow of energy. It will be explained more in the next slide
YUM!!!
1. Bacteria are produced by the heat the tubeworms put out (you will learn more next slide)
2. Zooplankton and Phytoplankton feed on the bacteria so energy transfers into them
3. Copepods and small crustaceans eat these and get eaten by large Crustaceans
4. Large Crustaceans get eaten by small fish or the other way around actually
5. These get eaten by the big predators like the Angler Fish and the Vampire Squid
Energy Transfer
Primary Producers
Secondary Producers
1. Dead Biomass is the “Primary Producer even
though it is dead because it comes from the dead things
that float down from the higher up zones.
1. Copopods, and large crustaceans, and fish, all eat the bacteria arund the vents
and/or they eat the dead biomass
2. Tube Worms are so to say, primary producers because
they are hydrothermal vents. They release black smoke in
which is a chemical that bacteria can survive on using
chemosynthesis.
Bigger predators eat these animals, and usually don’t
go around eating the Primary Producers.
Its like when we eat a hamburger…
