Aquatic Ec.
The producers of aquatic ecosystems
Algae, phytoplankton, water plants
Primary starts from no soil, secondary starts from soil.
What are the three types of biodiversity?
Genetic, Species, Ecosystem
What is the difference between marine and freshwater?
Salt content
After a beaver dam, what ecosystems are created?
The most productive marine ecosystems
Coastal; Coral reefs, estuaries, coastal wetlands
Two examples of primary succession
Glacier retreat, cooling lava from volcano
Which type of biodiversity is brought to mind normally by the term?
Species biodiversity
Where is there a mixing between salt and freshwater?
Estuaries
List at least three actions that beavers directly do to their environment?
Cut down trees, build dams, dig channels, raise the water table.
Plankton
Nekton
Benthos
Does not move on its own
Moves on its own
Lives at the bottom
Two examples of secondary succession
wildfire, old field, flooding
Having many different habitats in a biome would be known as which type of biodiversity?
Ecosystem diversity
Describe at least two adaptations for living in salt water
Gills to expel salt water, waxy coating on leaves, etc
List benefits of the new beaver system to other animals and plants
Space for new plants in the old woods and the new pond. Calmer waters to live in, new plants to eat. Increase in biodiversity.
Two types of plankton
Phytoplankton, zooplankton
What are the first plants to occur in primary succession? (vocab word)
Pioneer species
What is species biodiversity?
The number of species in an area
Which freshwater ecosystem is the most biodiverse and why?
The wetlands have still water and lots of sunlight.
Why was the Mississippi and important river to access?
From the Mississippi river you could travel to much of the US, from Montana to Tenessee.
Which aquatic ecosystem receives a lot of nutrients from other places in the world?
Estuaries
At the end of succession in our field out back, what plants would you expect to see?
If there are very few organisms of a species left, what is probably not very diverse in that species?
Genetic biodiversity
Give at least two examples of things that would happen if wetlands were destroyed?
Increase in flooding, worse pollution, etc
How did Chicago reverse its river?
They dug a channel to the Illinois river to divert the water away from the city of Chicago and down towards the Mississippi.
