Aquatic Ecology 2
100
This type of succession begins from scratch - the first step is lichens forming on bare rock.
What is primary succession?
100
Even though it may only happen once a year, if hundreds of Wilson's warblers eat food in a forest every year, the community is...
What is homeostatic balance?
100
The ability of an organism to withstand a change in the environment.
What is tolerance?
100
This material is carried by rivers and streams and gets into the water by the process of erosion.
What is sediment?
100
These are two transitional aquatic ecosystems.
What are wetlands and estuaries?
200
These changes occur in a community after a disturbance such as a storm, flood, or fire - the soil is not completely destroyed.
What is secondary succession?
200
This type of succession takes longer to occur.
What is primary succession?
200
Limiting factors such as predators, prey, and parasites are this type of limiting factor.
What are biotic factors?
200
Most of the freshwater on earth is found here.
What is inside glaciers?
200
This is the deepest region of the ocean.
What is the abyssal zone?
300
The last stage of succession forms this type of community.
What is a climax community?
300
Prairies, lawns, and athletic fields are all this type of community.
What is a sub-climax community?
300
Limiting factors such as temperature, soil chemistry, pollution, and sunlight are this type of limiting factor.
What are abiotic factors?
300
In a river or stream, the majority of organisms will be found here.
What is in slow moving water?
300
The aphotic zone in the ocean receives none of this.
What is light?
400
The first lichens (primary succesion) or plants (secondary succession) to show up in the new community
What are pioneer species?
400
The most common disturbance in Michigan that helps secondary succession.
What is fire?
400
This is the zone where the organism may experience decreased body functions or the inability to reproduce.
What is the zone of physiological stress?
400
This is the zone of a lake or pond that contains the most amount of organisms.
What is the littoral zone?
400
Freshwater and saltwater mixes in this aquatic ecosystem.
What is an estuary?
500
The forest climax community that we studied in our succession activity.
What is an oak-hickory forest?
500
The pond water that we looked at in class came from this type of pond.
What is eutrophic?
500
This is the ideal range for a limiting factor. The organisms are able to live and perform all life functions.
What is the optimum zone?
500
Lakes experience turnover (or over turn), which mixes around nutrients and oxygen, during these seasons.
What are spring and autumn?
500
Coral reefs are valuable ecosystems because of these two reasons
What is biodiversity and erosion prevention?
