The ocean contains a wealth of biodiversity, and most of this diversity lives in the sunlit area called
the euphotic zone
(see Distribution of Life, page 45, for more information).
What zone of the ocean has the most biodiversity?
The epipelagic zone
stretches from the surface down to 200 m and is home to the greatest biodiversity in the sea, largely because of the availability of sunlight that enables photosynthetic organisms to thrive.
What is the richest zone of the ocean?
- Gulf of Mexico. …
- Australia. …
- Japan. …
- South Africa. …
- Caribbean. …
- Mediterranean. …
- China.
What body of water has the most biodiversity?
Other Marine Biomes
That distinction goes to
estuaries
and coral reefs. They have the highest biodiversity of all marine biomes. An estuary is a bay where a river empties into the ocean.
What are the 4 ocean zones?
Like ponds and lakes, the ocean regions are separated into separate zones:
intertidal, pelagic, abyssal, and benthic
. All four zones have a great diversity of species. Some say that the ocean contains the richest diversity of species even though it contains fewer species than there are on land.
What are the 6 zones of the ocean?
The sunlight zone, the twilight zone, the midnight zone, the abyss and the trenches
.
What are the 3 zones of the ocean?
There are three main ocean zones based on distance from shore. They are
the intertidal zone, neritic zone, and oceanic zone
.
Which ocean zone is the warmest?
The epipelagic zone
tends to be the warmest layer of the ocean.
What are the 3 layers of the ocean?
The ocean has three primary layers. 2. The layers are the surface layer (sometimes referred to as the mixed layer),
the thermocline and the deep ocean
. 3.
Where is the most biodiversity found on Earth?
Brazil
is the Earth’s biodiversity champion. Between the Amazon rainforest and Mata Atlantica forest, the woody savanna-like cerrado, the massive inland swamp known as the Pantanal, and a range of other terrestrial and aquatic ecosystems, Brazil leads the world in plant and amphibian species counts.
Why do estuaries have high biodiversity?
Most estuaries occur where rivers empty into the ocean. Because river water is full of organic (dead plant and animal) matter,
estuaries are rich in nutrients
, and tiny water plants and animals, called plankton, are plentiful. … The pattern of salinity is crucial to the diversity of organisms that live in an estuary.
What are examples of biodiversity?
Most people recognize biodiversity by species—a group of individual living organisms that can interbreed. Examples of species include blue whales,
white-tailed deer, white pine trees, sunflowers
, and microscopic bacteria that can’t even be seen by the naked eye.
What ocean zone do sharks live in?
Habitat. Deep sea sharks live
below the photic zone of the ocean
, primarily in an area known as the twilight zone between 200 and 1,000 meters deep, where light is too weak for photosynthesis. This extreme environment is limited in both sunlight and food.
What are the 5 ocean zones?
The ocean is divided into five zones:
the epipelagic zone
, or upper open ocean (surface to 650 feet deep); the mesopelagic zone, or middle open ocean (650-3,300 feet deep); the bathypelagic zone, or lower open ocean (3,300-13,000 feet deep); the abyssopelagic zone, or abyss (13,000-20,000 feet deep); and the …
How deep is the abyssal zone?
The Abyssopelagic Zone (or abyssal zone) extends
from 13,100 feet (4,000 meters) to 19,700 feet (6,000 meters)
. It is the pitch-black bottom layer of the ocean. The name (abyss) comes from a Greek word meaning “no bottom” because they thought the ocean was bottomless.
What fish live in the abyssal zone?
Animals in this zone include
anglerfish
, deep sea jellyfish, deep sea shrimp, cookiecutter shark, tripod fish, and abyssal octopus also known as the dumbo octopus. The animals that live in this zone will eat anything since food is very scarce this deep down in the ocean.
