By Lukas Struppe CLICK TO ENTER THE DEEP SEA • 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! • 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 Yum! • 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. • No light is seen here • Anything living beyond this must be able to withstand Fun Fact: 11,000 psi. (we would get crushed) Abyssopelagic Comes • It is the largest living zone known to man frommiles the Greek • ≈115,000,000 square meaning nohigh bottom • The biomass is extremely here because of all the dead organisms that (but float there down is here. one) • 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 • 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. • Sadly there is no food web on these zones since so little is known. • There is A basic food web though Click Arrow For a Food Web on all three zones. Biomass • Dead Biomass • Tube worms YUM!!! Bacteria Crustaceans • Bacteria • Copepods • Large Crustaceans Small organisms • Small fish • Cucumbers Predators • Large fish • Squid, octopus e.t.c. ***Also Shows the flow of energy. It will be explained more in the next slide 1. 2. 3. 4. 5. Bacteria are produced by the heat the tubeworms put out (you will learn more next slide) Zooplankton and Phytoplankton feed on the bacteria so energy transfers into them Copepods and small crustaceans eat these and get eaten by large Crustaceans Large Crustaceans get eaten by small fish or the other way around actually These get eaten by the big predators like the Angler Fish and the Vampire Squid Primary Producers Secondary Producers 1. Dead Biomass is the “Primary Producer even 1. Copopods, and large crustaceans, and fish, all though it is dead because it comes from the dead eat the bacteria arund the vents and/or they eat things that float down from the higher up zones. 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. Its like when we eat a hamburger… Bigger predators eat these animals, and usually don’t go around eating the Primary Producers.
