MARINE BIOME Flashcards
The marine biome is
the world’s largest
biome, covering
______-quarters of the
earth’s surface.
covering three-quarters of the
earth’s surface.
It is the largest biome in the world.
marine biome
It takes up a whopping ___% of the
Earth and accounts for ___% of the
world’s water supply.
It takes up a whopping 70% of the
Earth and accounts for 90% of the
world’s water supply.
The average temperature is ____˚F,
but it is warmer near the equator where the direct rays of sun can
pierce the water and warm it.
39˚F
what is the microscopic marine
algae?
Phytoplankton
what are the primary producers of
the ocean?
Phytoplankton
is essential to this biome as it provides the __________ needed for algae and phytoplankton, which are the cornerstone of the ocean’s food
chain.
sunlight
Types of Ecosystems in Marine
Biome
❑ Ocean Ecosystem
❑ Coral reefs Ecosystem
❑ Estuaries Ecosystem
is the largest of the ecosystems
found within the marine biome.
Ocean Ecosystem
what are the four horizontal zones in the ocean ecosystem?
❑ intertidal zone
❑ pelagic zone
❑ benthic zone
❑ abyssal zone
The ________ zone is where the ocean meets the land, and it varies in appearance depending on its geographical location (rocky, muddy, sandy) and the time of the day.
intertidal zone
The ________ zone is further from the land and is home to many species of fish and some mammals, such as whales and dolphins.
pelagic zone
Below the pelagic zone is the ________ zone, which includes the sea floor.
benthic zone
5 pelagic zone layers:
❑ Epipelagic zone
❑ Mesopelagic zone
❑ Bathypelagic zone
❑ Abysspelagic zone
❑ Hadopelagic zone
The _________ zone is nutrient-rich, and supports a wide range of fauna, including bacteria, fungi, sea stars, marine worms, sea anemones, and fishes.
benthic zone
The primary flora in benthic zone is _________.
seaweed
fauna is _______
flora is ________
fauna = plants (in the ocean)
flora = animals (in the ocean)
The _________ zone is the deepest zone and is often dark, as light can not penetrate this deep.
abyssal zone
The ocean is divided into three vertical zones, which are based on depth: ___________, __________,
and __________ zones.
❑ euphotic zone (sea level)
❑ dysphotic zone (200 meters)
❑ aphotic zone (1000 meters and deeper)
The __________ zone is the area where light can penetrate and where the vast majority of photosynthesis takes place.
euphotic zone
This zone is around 656 feet (200 meters) deep.
euphotic zone
Marine life species that we can find in the euphotic zone
- Phytoplankton
- Zooplankton
- Krill
- Jellyfish
The middle layer is the ________ zone, also known as the ‘twilight zone’ of the ocean. This zone appears deep blue to black in color as less light can reach here.
dysphotic zone
Marine life species that we can find in the dysphotic or mesopelagic zone
- lanternfish
- dragonfish
- giant squid
- colossal squid
- king crab
