Lotic vs. Lentic
This is where aquatic plants in lentic ecosystems are located.
What is the littoral zone
When rivers enter open water such as an ocean and divide into multiple channels called distributaries.
Delta
Specific places where organism reside and the primary feature is the substrate.
what is benthic zone
this is the impact of sediment and nutrients brought by storm water runoff on a lentic ecosystem
What an increase in pond succession
The open water portion of a lake where larger fish spend most of their time
What is the limetic zone
Light penetrates through part of this zone of the lentic system not associated with the shore.
What is the limnectic zone.
The amount of water flowing past a certain point in a given unit of time.
What is discharge or flow. I will also accept velocity
organism that eat plankton from the water with special mouths and adaptations to gills
What are collectors. I will also accept filter feeders.
in this lentic ecosystem oxygen levels are high during the day and then fall low at night
What is pond
An abiotic factor that is fairly consistent in the lake
What is the amount of DO
Lotic zones associated with fast moving, shallow water with small waves
What are riffles
Humans build dams stopping the water flow
Form a lake/reservoir
these organisms are located in deep parts of the lake ecosystems where there is too little sunlight or oxygen for plants and algae to grow
What are bacteria and decomposers
The lentic system in this picture
What is a pond
In a lake this abiotic factor is layered
What is temperature
An over abundance of nutrients
What is eutrophic
absorbs excess nutrient from runoff from getting into the pond and hold the soil in place preventing erosion
What is a buffer zone
this organism is the greatest amount of living material in a pond
What is plankton
this adaptation to aquatic plants prevents the plant from drying out during periods of low water where the plant may become exposed to the air
What is a wax coat and slime
The area where plankton are located in a pond
What is the photic zone
The lentic zone where light does not penetrate.
What is the aphotic zone
erosion in the watershed and plant materials accumulate in the bottom
what is pond succession? I will also accept life of a pond
this determines general structure and function of stream communities as they flow and combine together
What is stream order.
plants in aquatic ecosystems are able to obtain nutrients in this way
What are porous stems and leaves
A ring around the shore reaching out as far as the rooted plant life can survive
What is a littoral zone
