1. Aquatic Ecosystems
5.L.2.1 I can compare the characteristics of several common ecosystems, including estuaries and salt marshes, oceans, lakes and ponds, forests, and grasslands.

2. Aquatic Ecosystems
Aquatic Ecosystems may be fresh water (lakes and ponds) or saltwater (oceans, estuaries, and saltwater marshes
ocean
lake
estuary
pond
Saltwater marsh

3. Lakes & Ponds
Large (lakes) and small (ponds) bodies of fresh water surrounded by land
Ponds shallower, stays same temp from top to bottom

4. Lakes & Ponds
Plants and algae grow around edges where water is shallow
Snails, frogs, turtles, ducks, beavers, fish, catfish, bass & trout

5. Oceans Large bodies of saltwater divided by continents.
Oceans have many types of ecosystems depending on conditions (sunlight, temperature, depth, salinity.
Most organisms live where the ocean is shallow. (from the shoreline to the continental shelf)

6. Oceans
Some organisms that live in the shallow ocean are drifters (jellyfish or seaweed), swimmers (fish), crawlers (crabs), and those anchored to the floor (corals)
In deep water, plankton float on top. Others are whales, turtles, sharks, fish, octopus

7. Estuary
Where fresh water from a river meets and mixes with salt water from the ocean
High tide – salt water flows in
Low tide – salt water flows out

8. Estuary
Organisms must be adapted to live in different amounts of salt throughout the day
Shrimp, crabs, oysters

9. Salt Marsh
A salt marsh is a type of estuary that act like an enormous filter, removing pollutants such as herbicides, pesticides, and heavy metals out of the water flowing through it.
