This concept is also described as "survival of the fittest".
What is natural selection?
the variety of life on earth
What is biodiversity?
the study of how living organisms interact with each other and with their physical environment
What is ecology?
What is the carrying capacity of this leopard seal population?
What is 7,500?
We saw evolution happen during the Industrial Revolution in this species.
What is the peppered moth?
Humans breeding dogs to produce certain breeds or characteristics is an example of what?
What is artificial selection?
Biodiversity tends to increase as you move from the polar regions to this imaginary line.
What is the equator?
a group of organisms of the same species living in the same area
What is a population?
The largest percent reduction of living budworms in this table occurs due to what?
What is dispersal?
This state fish population is in decline due to invasive species.
What is the cutthroat trout?
a mechanism of evolution where the frequency of traits in a population changes over time due to random chance
What is genetic drift?
This occurs when biodiversity is lost.
What is extinction?

What is a cladogram?
According to this table, what type of mathematical relationship exists between the deer and wolf populations?
What is an inverse relationship?
This is Miss Legg's favorite North American bird. It is a secondary consumer because, in addition to eating fruit, it listens for tasty worms moving under the soil and extricates them with its beak.
What is the American robin?
A small group of birds becomes separated from the mainland and establishes a population on an island, and the new population has different allele frequencies than the original population.
What is the founder effect?
Give me caffeine! These two popular consumable crops are grown together in Costa Rica to help maintain biodiversity of the ecosystem.
What are coffee and chocolate?
a permanent change in the DNA or RNA sequence of an organism's genome
What is a mutation?
Ladybugs are carnivorous! At what level of this ecological pyramid should they be placed?
What is the secondary consumer level.
This apex predator inhabits western and central Australia.
What is the dingo?
This occurs when biodiversity is drastically reduced after a natural disaster.
What is the bottleneck effect?
A forest is divided into several small patches by roads and housing developments. What threat to biodiversity does this illustrate?
What is habitat fragmentation/urbanization?
one of two or more alternative versions or forms of a gene at a specific location on a chromosome
What is an allele?
Grass populations growing near contaminated mine sites evolve metal tolerance, while adjacent populations on normal soil do not. This results in the formation of new species (speciation). What type of speciation occurs for this example?

What is parapatric?
New research suggests a volcanic eruption resulted in the spread of this bacteria, which ultimately caused the Black Plague in Europe.
What is Yersinia pestis?
