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

INTERACTIONDeep 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: PRODUCERSBacteria:

-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
