FreshwaterBiomes
• Are made of water with no salt
Ex. Rivers, streams, lakes, ponds, swamps• Are shaped by abiotic factors
Ex. The speed at which the water is moving

Tributary• Each creek or stream of water that joins a larger trickle or stream.
So, where does the water come from that enters the tributary?

Fast-Moving Water• Forms as more tributaries join a stream and then
a river.• Organisms have adaptions to avoid being swept
away.• Ex. Algae, moss, tadpoles, fish, clams

Slow-Moving Water
• As a river grows wider and slower it meanders.• Meander-to flow in a curved pattern on the land.
• Deltas may form Ex. Mississippi & New Orleans & Dry Deltas on Mars

Slow-Moving Water Animals
Ex. Dragonflies,
Water Striders,
& Fish

Still Waters
Ex. Lakes & Ponds• Have 3 Zones
-Littoral
-Open-Water
-Deep-Water
Check out your Still Water chart.

Littoral Zone
• Closest to the edge of land.• Lots of light means lots of plants near the shore.
Ex. Cattails, pond weeds, water lilies

Littoral ZoneAnimals
Ex. Snails, clams, worms, frogs, salamanders, turtles, & fish

Open-Water Zone
• Only goes as deep as light can reach
Ex. Bass, trout, phytoplankton
![Page 13: What are some characteristics of freshwater biomes?](https://reader036.vdocuments.us/reader036/viewer/2022081419/56649ec45503460f94bce262/html5/thumbnails/13.jpg)
Deep-Water Zone
• No light
Ex. Catfish, carp, crustaceans, fungi, bacteria• Organisms feed on dead material.

Wetlands
• Area of land where the water level is near or about the surface of the ground for most of the year.
• Control flooding• Replenish underground water

MarshWetland
• Treeless wetland• Found in shallow water along shores of lakes,
ponds, rivers, streams
Ex. Reeds, wild rice, muskrats, turtles

SwampWetland
• Trees and vines grow here• Located in low-lying areas beside slow rivers
Ex. Willow, oak, elm trees, Spanish moss,
Poison ivy, snakes, birds

So, how can lakes or ponds disappear?
1. Water carries material to the standing water
2. Dead material then settles to the bottom
3. The lake or pond slowly fills up
4. Lake…marsh….forest.
