Sea Animals
Marine
biology marine organisms a science studying the case of living organisms in the
ocean or other marine surfaces . Where she lives most of the marine organisms
in the sea and others on the ground, the two species are classified on the
basis of the environment rather than focusing on the classification. And marine
biology differs from the marine environment where Albeolojba interested in how
marine organisms interact with the environment. And help to determine the
nature of our planet as well as they contribute greatly to the oxygen cycle ,
and participates in regulating the Earth 's climate . The beach is part of the
marine life, which also includes part of the marine biological life , which
include a lot , Almjhriaat , including most of the phytoplankton and
zooplankton . The establishment of marine reserves showed the results of a
long-term and often contributed to the rapid increase in the abundance and
diversity and productivity of marine organisms. At the time seem obvious
protection benefits for organisms that spend most of their time inside the
marine environment , where it can provide protection for migratory species in
the event of protection in the stages of weakness, especially the protection of
breeding sites and her lap. And know the marine environment vast water space
which is characterized
by a
substantial increase in the proportion of dissolved solids in which the
increase in freshwater organisms include plant and animal and non-living
components exist between the components of the environment relations work on
Atzanha . Include large numbers of diverse organisms in the forms and colors
and ways of living types, and participates in the vast number of diverse
neighborhoods set of properties known manifestations of life. Some argue that
the water does not exceed being one of the basic requirements of human life.
Interested in the majority of sectors, with a purity of water and the potential
lack of resources. But we believe that the waters of the seas and oceans are no
less important than drinking water , since it constitutes an important aspect
of normal life in general. And contribute to marine organisms in maintaining
the ecological balance and ensure the purity of the sea and the quality of its
waters . The ocean water is a major source of food and mineral salts , it is
also an important means of trade , transportation and recreational activities.
And increasing transformation of man to rely on the seas and oceans for the
main food through direct fishing or fish farming for
use in animal feed. The approximately 10% of the
protein consumed by man from the ocean . These facts underscore the
inevitability of action to take serious and quick steps to protect the
environment and marine organisms from the risk of contamination . Living
organisms many in the sea like some other species of animals that live in the
sea such as starfish and jellyfish also called fish but not fish does not
contain her body on the bones , as well as another type of aquatic organisms
known organisms molluscan of coincidences , such as shellfish different , and
there are crustaceans such as shrimp and shrimp . Has increased interest in marine
organisms and to increase the utilization of food or medical terms and also to
prevent its publication . The diversity of marine organisms large and not easy
to restrict or even classified because it has many properties and a variety of
lifestyles as well as the different functions of its members and methods and multiply. Some marine organisms extracted
oxygen by the gills and some of these animals by lung and breathing so his rise
to the surface to renew the air , there Fish prefer to live close to the
surface or deep , medium - and there Fish prefer the bottom.
Some marine organisms
Fish and marine mammals in fisheries contribute
to the development of the human economy , global fisheries are concentrated in
front of the coast of the northeastern United States of America, and the
western coasts of Canada and the west coast of South America , and the east
coast of Asia.
Algae reliable staple food in some countries ,
such as Japan , as extracted from agar material , Aldjin and first used in
making desserts ( jelly ) , medical laxatives and sulfa compounds and vitamins.
Used article Aldjin ( which features Blzojtha and non - porosity ) in the
manufacture of materials and Alguetaouan is carried out of the water .
Sponge , a sea creature living in the water
tropical and sub - tropical
greenhouse , which is characterized by high salinity , live in
shallow water between 10 to 50 meters. The company 's main fisheries some
sponge coast of the United States of America , Greece and the West Indies.
Types of inland marine systems : hunted fish and
other aquatic resources from a wide range of ecosystems , including freshwater
lakes and marshes, floodplains , rivers and waterways , and most natural
sources. And linked to the status and trends of ecosystems to aquatic organisms
closely related to the conditions prevailing in the neighboring terrestrial
ecosystems . However, all water bodies inland almost been modified to some
extent a result of the interventions of human (such as the effects of enrichment
of fertilizers and excessive animal waste ) as well as converted within the
structures of the local community appointed by where there are a result of
biological diversity - through the introduction of new species - and providing
them with seed from Ann to another. Therefore , it is necessary to look at all
the internal ecosystem to aquatic organisms in terms of watersheds and basins
in which there is . Coastal waters : including estuaries and large lakes ) form
the link between the environment and those of marine , freshwater and between
continents and oceans. And play a key role as nurseries for many marine
species. Coral reefs: mostly represents the kind of ecosystems in tropical
areas where less than warm waves or freshwater input . These reefs are important
for the island countries , but it is weak, rich in biodiversity and are
strongly influenced by inland waters and internal activities . Continental
shelves soft -bottom: that appear in front of the major river delta systems
from which they get the exact sediment that is considered one of the tag ( such
as gravel , sand and mud ) . And affected by this plaque , which extends to a
depth of 200 meters , usually strongly remnants of the rivers from which they
get to high productivity , which govern the natural variations . Open ocean
represents the largest area and volume of marine ecosystems , although the
biological and fishery production per unit area is far less than other
ecosystems . And seamounts element marked elements of the ecosystem of the oceans
open and home to some of the resources weak long-life that live in the deep sea
(such as Conch Orange (Oceans frozen : (ie the Antarctic Ocean and the Arctic
Ocean ) is one of the ecosystems on the high productivity in certain seasons
and are operational active nutrient-rich paid by ocean currents and on which
they depend important fishery resources ( such as fish , krill and whales and
small crustaceans ) and other species ( such as sea birds and seals) .
