Deep Sea Biome
Lauryn Mitchell,
Tai Schroeder, Katherine Truong
ABIOTIC Factors:
Light: Very dark/ no sunlight
Temperature: 2-4 degrees Celsius
Pressure: ranges from 20atm to
over 1,000atm
Oxygen: oxygen-poor
environment
Turbidity: High, lots of sediment
Nutrients: A lot (mostly from dead
organisms)
BIOTIC Factors:
HUMAN
INTERACTION
Deep Sea Trawling:
-Reduces the biodiversity
-Destroys the coral reefs
-Ruins habitats
-Takes away soil nutrients
-Over fishing
Offshore Oil Drilling:
-Destroys habitats
- creates potential risk of oil
spill (BP)
-Beached Whales (sonar
hurts ears)
-Ruins deep sea coral
Adaptations: PRODUCERS
Bacteria:
-use volcanic vents
-hydrogen sulfide
-tube worms
Deep Sea Plankton:
-flat bodies and spines
Deep Sea Coral:
-attach themselves on a solid
surface
-rely on ocean current
-grow tall to catch krill and
other food
Adaptations: CONSUMERS
Anglerfish:
-reproductive adaptation
Fang tooth:
-big mouth without a jaw
-strong sense of smell
Hagfish:
-strong sense of smell and
touch because of bad eye
sight
Tundra Biome
ABIOTIC Factors
-Strong winds
-Rainfall
-Permafrost
-Soil
-Short summer days and long
winter days
BIOTIC: HUMAN
INTERACTION
Air Pollution/ Smog:
-Contaminates the lichen
which provides food for
many animals in the tundra
- decreases biodiversity
-Destroys habitats
Oil, Gas and Mineral
Exploration:
-Ruins habitats
-Creates a risk of an oil spill
-Disturbs the physical
landscape as well as the
ecosystem
Adaptation:
PRODUCERS
• Furry or waxy coating on
leaves
- resists cold and wind
- ex. Woolly lousewort
• Retains dead leaves
- protect against wind and
cold
• Low growing
- stays out of wind chill
- ex. Bearberry
Adaptations:
CONSUMERS
• Feathers/Fur
- reduces heat loss/
resists cold
- ex. Ptarmigan
• Short appendages
- reduces heat loss/
resists cold
- ex. Arctic Fox
• Alaskan blackfish
- can lower the freezing
temperature of its cell fluids
