Lentic Systems
Ecosystems with standing water, like lakes and ponds.
What are lentic ecosystems?
An ecosystem that flows in one direction, is normally oxygen rich, and is shallower, narrower, and longer than a lake.
What is a lotic ecosystem?
Fast moving runs, rapids, and riffles can cause this process.
What is erosion?
What is submerged vegetation?
This fast-moving part of a stream is in the center.
What is the Run?
The zone of a lentic ecosystem where light enters and emergent plants are found.
What is the littoral zone?
A stream with three or more tributaries (smaller streams) flowing into it.
Sand or gravel bars made of sediment form in slow parts of streams due to this process.
What is deposition?
This type of microscopic plankton can convert energy using photosynthesis.
What is phytoplankton?
What is the Bar?
The middle zone of a lentic habitat, where fish live.
What is the limnetic zone?
A deep, slow-moving part of a stream with eddies.
What is a pool?
In an extreme rain event, water overflows the stream channel and runs into this area.
What is a flood plain?
This spongy type of plant is found in wetlands like bogs and fens.
What is peat moss?
This fast-moving water provides fun for raft rides.
What are Rapids?
A transition zone between water and land.
What is a wetland?
Part of a lotic ecosystem that provides habitats for small fish, flowing water, and oxygenation.
What is a riffle?
Erosion can be caused when impervious cover increases this type of flowing water.
What is run-off?
This type of free-swimming organism can be found in pools of lotic ecosystems and the limnetic zone of lentic ecosystems.
What are fish?
This slow-moving part of the stream contains eddies.
What is the pool?
A zone of the lentic ecosystem with a total lack of light and no photosynthesis.
What is the profundal zone?
A type of stream that stops flowing for at least one week at year.
This type of zone prevents run-off and erosion from affecting the stream.
What is a riparian zone?
"Sticky" organisms like algae and snails that cling to rocks, logs, and other debris.
What are periphyton?
This slow-moving part of the stream can be found in shallower areas.
What is a Glide?
