Transcript of Aquatic Ecosystems
How can you compare the characteristics of several common ecosystems, relationship among their organisms, and describe how all of the organisms in an ecosystem are interconnected.
2 Types of Aquatic Ecosystems
1. Marine Ecosystems
2. Freshwater Ecosystems
The ocean is where salt water generally exists.
The intertidal zone (tide pool) is at the edge of the ocean, where the waves break. Many organisms live here because sunlight can reach deep and the water is warm, making food abundant.
We will fill out our guided notes while going through prezi.
3 zones of the ocean
Clams, periwinkles, barnacles, sea urchins, mussels, crabs, sea stars, sea anemones, sponges, jellyfish, fish, lobster, shrimp
Algae, sea lettuce,
The near-shore zone extends from the intertidal zone to the area that is about 600 feet deep.
zooplankton, dolphins, whales, sharks, fish, krill, porpoises, jellyfish, shrimp, and coral
sea grasses and kelp
The open-ocean zone is deeper and covers the majority of the ocean.
Plankton float in the upper regions of the water.
Some organisms swim to the surface to find food or for air, while others live closer to the bottom.
zooplankton, many of
the ocean animals we know, including: fish, whales, sharks, squid, flying fish, turtles,
algae, and sea weeds
Tide pools form in zones of rocky shoreline where ocean and land
meet—strips of shore, sometimes only a few yards wide, where everything is covered and uncovered by tides each day.
Plants and animals are the same as
the intertidal zone of the ocean.
found in clear, tropical oceans.
form in waters from the surface to about 150 feet (45 meters) deep
need sunlight to survive.
The three types of reefs include:
occur along shorelines of continents and islands and are commonly found in Hawaii and the Caribbean
found farther offshore
series of low coral islands surrounding a central lagoon, frequently found in the
area where seawater mixes with freshwater.
Can be found along the coast.
As tide rises, saltwater comes into the estuary. Freshwater comes down the rivers and creeks and mixes with the saltwater (brackish water). This can make the estuary very salty.
They can even be saltier than the ocean!

crocodiles, marine mammals,

found on every coast
frequently submerged by tides
contain a lot of decomposing plant material
have a sulfurous rotten-egg smell
fiddler, hermit, and stone crabs, snails, mussels, worms, fish, and shrimp
Salt bushes and grasses
surrounded by land.
ponds are usually more shallow
temperature of the water in a pond usually stays the same from top to bottom
different types of fish,
turtles, or beavers
water lilies, cattails
Wetlands are areas of standing water that support aquatic plants. Examples are marshes, swamps, and bogs.
Otters, minks, beavers, some fish, crayfish, shrimp, tadpoles, insect larvae, alligators, birds, insects, frogs
algae, floating plants, duckweed, cattails, grasses, shrubs, wildflowers
made up of any of body of water that is made of freshwater such as lakes, ponds, streams, and rivers.
cover roughly 20% of the Earth and are in various locations spread out all over the world. m
most consist of moving water and contain many types of fish

Coral Reefs are the
rainforests of the ocean!

Salt Marsh wildlife
Lakes and Rivers
(During the dry season there may not be much freshwater flowing down the rivers. This can make the estuary very salty. Also, during the dry season water evaporates out of the estuary making it even more salty.)
