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
Marine Ecosystems
Ocean
Estuaries
Tide pools
Coral Reefs
Salt Marshes
Ocean
The ocean is where salt water generally exists.
Intertidal Zone
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.
Freshwater Ecosystems
Aquatic Ecosystems
Essential Question
We will fill out our guided notes while going through prezi.
3 zones of the ocean
Intertidal zone
Near-shore zone
Open-ocean zone
Animals
Plants
Clams, periwinkles, barnacles, sea urchins, mussels, crabs, sea stars, sea anemones, sponges, jellyfish, fish, lobster, shrimp
Algae, sea lettuce,
kelp
Tide Pools
Near-shore zone
The near-shore zone extends from the intertidal zone to the area that is about 600 feet deep.
Animals
Plants
Coral Reef
zooplankton, dolphins, whales, sharks, fish, krill, porpoises, jellyfish, shrimp, and coral
sea grasses and kelp
Open-ocean zone
The open-ocean zone is deeper and covers the majority of the ocean.
Plants
Animals
zooplankton, many of
the ocean animals we know, including: fish, whales, sharks, squid, flying fish, turtles,
octopus, tubeworms
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:
fringing reefs
occur along shorelines of continents and islands and are commonly found in Hawaii and the Caribbean
barrier reefs
found farther offshore
atolls
series of low coral islands surrounding a central lagoon, frequently found in the
Pacific.
Estuaries
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!
Animals
birds, fish, shellfish,
crocodiles, marine mammals,
marine worms
Plants
pickle weed, salt grass,
sea grasses, seaweeds,
mushrooms
Salt Marsh
a habitat within an estuary.
found on every coast
frequently submerged by tides
contain a lot of decomposing plant material
have a sulfurous rotten-egg smell
Animals
fiddler, hermit, and stone crabs, snails, mussels, worms, fish, and shrimp
Plants
Salt bushes and grasses
surrounded by land.
ponds are usually more shallow
temperature of the water usually stays the same from top to bottom
Lake/Pond
Animals
different types of fish,
amphibians, ducks,
turtles, or beavers
Plants
Algae, ducktails,
water lilies, cattails
Wetlands are areas of standing water that support aquatic plants. Examples are marshes, swamps, and bogs.
Wetlands
Animals
Otters, minks, beavers, some fish, crayfish, shrimp, tadpoles, insect larvae, alligators, birds, insects, frogs
Plants
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
Let's visit an example of an Intertidal Zone!
Coral Reefs are the
rainforests of the ocean!
Stop at 4:20
The ocean
has layers??
Life in the estuary!
Salt Marsh wildlife
Lakes and Rivers
Freshwater
Wetlands
(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.)
