Biodiversity
The number of different ecosystems found on Earth is this.
What is ecosystem biodiversity?
A heat wave covers Arizona killing 40% of species populations. This is an example of this type of limiting factor.
What is an abiotic limiting factor?
An example of this threat is a chemical leeching out hurting the ecosystem.
What is pollution?
This is how biodiversity can be defined.
What is the abundance of living organisms in an area?
Biodiversity is significant for these two reasons.
What is ecological and economical significance?
A hurricane occurs and wipes out 25% of a population. This would be an example of this type of limiting factor.
Too many quail are hunted, therefore they can no long reproduce the next year.
What is overharvesting?
Variety or variation within a species genes is this.
What is genetic biodiversity?
Multiple climate zones on a continent is an example of this type of biodiversity.
What is ecosystem biodiversity?
There is not enough algae in a lake to sustain a high fish population than 5,000. This is an example of this type of limiting factor.
What is a biotic limiting factor?
Due to dam construction, a population of salmon lose their breeding grounds. Example of this type of threat.
What is habitat loss?
High biodiversity is important for this in an ecological sense.
What is ecological stability?
Birds of the same species but with different beak sizes represents this type of biodiversity.
What is genetic biodiversity?
These are 5 examples listed in class of abiotic limiting factors.
What are:
Weather
Water
Minerals
Temperature
Sunlight
As this threat grows so do the other threats.
What is population growth?
In one area where there are multiple different organisms would represent this tye of biodiversity.
What is species diversity?
This is the "Tragedy of the Commons" phenomenom.
What is when a resource is overexploited when no one owns the resource, so no one ensures it is not overused?
Double Jeopardy: These are 5 examples listed in class of biotic limiting factors.
What are:
Amount of Predators
Prey (Availability of food)
Producers
Decomposers
Human activity
Cane toads are introduced into AZ where they eat all the native reptile species.
What is an invasive species?
These are the 5 threats to biodiversity in order.
What is
Habitat loss
Invasive species
Pollution
(Human) Population Growth
Overharvesting
