Water Biomes
Water-based regions home to a unique group of living things.

2. Three Types of Water Ecosystems
Saltwater- oceans and seas
Freshwater- streams, rivers, lakes and ponds
Brackish- where salt water and fresh water meet

3. Wetland Also known as swamp, marsh, or bog
Land covered with shallow water for all or part of the year
Water comes from rain, melted snow, underground spring
Marsh-grassy with reeds and cattails near river or lake
Bog- found in cool climate, spongy peat moss
Swamp- forested wetland full of trees and shrubs

4. River A ribbon of water that weaves over land
Constantly moving and changing
Can carve canyons and form waterfalls
Water comes from melted snow, springs, rainwater, underground
Water flows downhill
Underwater plants anchor in the river bottom
Water level drops and rises depending on rain fall.

5. Lake A pool of freshwater that fills low spots in land
Form from mountain snow, natural springs, along rivers, or behind dams
Trees line the sides of the lake
Water lilies grow on top of the water
Tall grasses are on the water edge

6. Estuary Where a river meets the ocean Part wet part dry
Forms brackish water (fresh water and salty water mixed)
Found on edges of continents and islands
Experience high and low tides
Mud is full of nutrients

7. Ocean Covers 75% of earths surface Very salty Largest water biome
Waves move water and has high and low tide
Sea weed and algae grow
Deep water gets no light so few producers and cold temperatures
