Transcript MarineBiome

Characteristics of the Marine
Biome
• cover 71% of the Earth’s
Surface.
• Some places of the ocean
floor are deeper than Mt.
Everest is high.
• 96.5% of the ocean is pure
water
• 3.5% is dissolved compounds
that typically runoff from rivers
or rainwater.
Factors Effecting the
Composition of Marine Waters
• Air
– The levels of oxygen (O2) and carbon dioxide
(CO2) in the water are greatly effected by the air
• Rivers and Runoff from Land
– add minerals and sediment
• Disasters
– Hurricanes, typhoons, and cyclones weather and
erode the coastal regions washing sediments into
the ocean
– Human activities
Components of the Marine
Biome
• Abiotic (nonliving)
– Water
– Sunlight/darkness
– Minerals
– Dissolved gases
• Biotic (living)
– Producers
– Consumers
– Decomposers
Aphotic Zone
Levels of Light
in the Ocean
• Photic zone
– Light fills the water at
this level
• Twilight zone
• Aphotic zone
– Depths where no
sunlight exists
(Click image)
– Transition zone
between light and
absolute darkness
Primary Consumers
• Eat the producers herbivores
– Sea urchins – eat kelp
– Sea butterflies – feed on
phytoplankton
– Parrot fish – eat algae
Secondary Consumers
• Eat the primary consumers –
carnivores or omnivores
– Jelly fish – eat small fish
– Clown fish – eat small
invertebrates
– Sea otters – eat sea urchins
Tertiary
Consumers
• Eat the secondary
consumers
– Polar bears – eat
seals, walrus, and
beluga whales
– Great White sharks –
eat dolphins, sharks,
whales, sea lions, sea
turtles and sea birds
– Bull sharks – eat
dolphins, rays, sea
turtles and sea birds
Decomposers
• Filter Feeders – remove dead
materials floating in the water
– Ex. Tube worms and anemones
• Bottom Feeders – break down
dead materials that has made its
way to the ocean floor
– Ex. Sea Cucumbers and Star Fish
