A group of organisms of the same species living in the same area.
What is a population?
100
Populations usually decrease dramatically when they surpass this.
What is their carrying capacity?
100
Biodiversity includes these three ares.
What is species, genetic, and ecosystem biodiversity?
100
These areas, such as tropical rainforests and coral reefs, contain an incredible amount of biodiversity but only occupy small percentages of earth's land mass.
What are biodiversity hotspots?
200
The amount of organisms in a given area.
What is population density?
200
When all members of a population, in all ranges, disappear, this occurs.
What is extinction?
200
Biodiversity has value in these areas (at least 3)
What is direct and indirect economic, scientific, and aesthetic values?
200
Using resources at a rate in which they can be naturally replenished.
What is sustainable use?
300
The total area inhabited by a population.
What is its range?
300
Disease, predation, parasites, and competition all increase when a population increases and are therefore this type of factor.
What is density dependent factors?
300
The biggest threat to biodiversity.
What is habitat loss?
300
The Endangered Species Act of 1973 and C.I.T.E.S are examples of these.
What are laws to protect biodiversity?
400
Natural disasters such as floods and forest fires effect all populations regardless of size and are therefore this type of factor.
What are density independent factors?
400
This occurs when organisms or resources are taken from an environment faster than they can naturally be replaced.
What is overexploitation?
400
Utilizing cattails to purify a degraded ecosystem is an example of this.
What is bioremediation?
500
Even though the size of the Mississippi flyaway population of Canadian geese fluctuates dramatically throughout the year (due to mortality and natality), the population remains relatively stable. Therefore, the population is said to be in _____________.
What is homeostasis?
500
These were either accidentally introduced or were purposely brought to increase biodiversity, but with negative effects on endemic species.
What are invasive species?
500
Why does conservation of biodiversity sometimes conflict with human needs or cultural ideas? What kinds of things can be done to reach a compromise in these areas?
