Marine
Ecosystems
By Ben Paterson and
Aidan Harris
Introduction
Marine ecosystems are ecosystems that
are under water, because marine means
something to do with water. These
ecosystems can be in lagoons, lakes,
oceans, seas, swamps and wetlands,
basically anywhere there is water. Marine
ecosystems can even exist in puddles,
made up of microbes and bacteria.
Oceans
The biggest marine ecosystem exists in
the worlds seas and oceans, containing
many more species of animals and plants
than on land. The biggest creatures on
earth, whales, are only found in seas and
oceans, as well as some of the smallest
creatures on earth, plankton and algae.
Lakes, Rivers and Creeks
Lakes are bodies of water that are inland
from seas and oceans, and have a wide
diversity of marine wildlife. Fish, some
insects, algae and small lake weeds.
Rivers are found all over the world and are
rich in fish and plant life. Creeks are small
rivers that are also found all around the
world, but there are a lot in Australia in
particular. They contain creatures such as
small fish and yabbies or crayfish.
Puddles
Even in puddles an ecosystem can exist,
made up of small bacteria, algae and
microscopic organisms. These
ecosystems don’t usually last long,
because the puddle usually dries up. But
sometimes an ecosystem can flourish in a
puddle and last for a long while, until the
puddle dries up.

Climate Change
Climate change will have a large and
decisive effect on marine ecosystems all
over the world. In and around Australia the
effects could be devastating and could
effect all of us, near the coast or inland.
Sea levels could rise and flood large areas
of land, or we could have droughts lasting
for many decades.
Seas and Oceans
Sea levels could rise and flood large areas
all around the globe, but particularly here
in Australia. We may lose many of our
famed beaches and oceans will become
warmer, destroying the corals reefs and
driving some species of creatures to
extinction.
Inland Water Systems
Inland Australia is filled with creeks, rivers,
lakes, ponds and dams. If climate change
causes prolonged droughts many of these
waters ways will dry up, causing loss of
habitat for some species and loss of
drinking water for others.
What we can do
To stop climate change we must do
several things to change how we live and
work. People might think that one person
might not make a difference, but you can.
If one person starts to do something about
climate change other people might follow.
Things to help
To help with climate change you can
change lights to eco globes, which save
energy. You can turn off lights if your not in
the room, turn off appliances if they aren’t
being used. Recycling and using grey
water can also help to prevent climate
change.
