The Coral Reef The Coral Reef is Coral reefs are warm, clear,
shallow ocean habitats that are rich in life.
Slide 3
Map The coral reef is the pink bits.

3 Species Sea Snakes: Sea Snakes are Snakes that can spend
there time underwater for 2 hours between breathes. Dolphin:
Irrawaddy and Indo-pacific Humpback Dolphins feed on fish in
shallow water, especially in estuaries or river mouths. Birds:
White-breasted sea eagles live on the coast and on the islands.
They find it hard to take off from the water, so they fish by
snatching their prey from the water's surface.
Slide 5
3 Plants Coral: They are giant clams can grow to be more than 1
metre long and can be at least 70 years old. They are the largest
bivalve mollusc that has ever existed on the planet. Seaweed:
Seaweeds contain many compounds useful to humans: carrageenans or
agar (from red seaweeds) or alginates (from brown seaweeds) are
used in ice cream, instant puddings, salad dressings, printers ink,
cosmetics, in pharmaceuticals and to coat pills. Most seaweeds are
not poisonous to humans but a few such as Caulerpa, are poisonous
to grazing animals. Seagrass: Seagrasses are different to seaweeds
and algae because they have true roots and they are flowering
plants. Seagrasses are the only flowering plants in the whole sea.
They are important food for turtles and dugongs.
Slide 6
Abiotic Factors of the Coral Reef The Temperature: of the Coral
Reefs Water is about 25 29 Celsius. The type of Coral's you find in
the Great Barrier Reef are hermatypic corals - meaning they contain
zooxanthellae algae and are colorful. These corals can lve in the
range water of 18 33 celsius. Nutrients: Coral Reefs only survive
in Clear Water, with low sediments, These waters would not
naturally have many animals living in them but because of the lack
of nutrients, but since corals live here, many thousands of animals
survive by eating the coral, or the animals that eat the coral.
Light: Light is really important for coral reefs The reason corals
are able to survive in non-nutritious water is because of the
zooxanthellae algae produces food for the coral as well as for
itself. In order to photosynthesize to produce food however, the
algae needs light. Without light, this whole ecosystem cannot
exist. Salinity: Coral reefs tend to live in salty water, surviving
in a range of 27 40 parts per thousand but preferring at 36 ppt.
Wave Motions: Wave motions help take away the waste in the Coral
Reef and bring food.

How has science helped to discover the resources that we can
use? Science has helped us understand the elements of the matters
and how to utilize them for our benefits.
Slide 8
human activities that affect your biome. Coral Reefs around the
world are dying. In particular, Coral mining, pollution,
overfishing, blast fishing and digging of canals and access into
islands and bays are serious threats to these eco-systems. 10% of
the worlds reef is already dead and is estimated that about 60% is
in high risk. Once an Oil Spill happened in one of The Coral Reefs,
so there was a coal- carrying ship that strayed outside a shipping
lane in protected waters and was leaking oil on Australia's Great
Barrier Reef and was in danger of breaking apart. Coral Mining
Mining also destroys coral. Sometimes coral pieces are removed for
use as bricks or road-fill, or, sand and limestone from any of the
coral reefs are made into cement for new buildings, but corals
aren't only removed from their habitat for construction, they are
also sold as souvenirs. Coral curios and jewelry are often sold to
tourists and exporters in the markets.
Slide 9
How has use of natural resources affected the environment,
Economics, or Society? Oil Spills has affected the Coral Reefs and
is causing pollution to the sea. Cutting down trees makes pollution
to the air and after all trees have been destroyed, then there will
be no more oxygen. Natural resources built large economies and
brought income to many countries by exporting these natural
resources like Oil, Diamonds, Coals and many many more.
