The study of the interactions between organisms and their environment.
What is ecology?
100
An organism's role or job in its environment.
What is niche?
100
The definition of evolution.
What is a change in the allele frequencies of a population over time?
100
Darwin collected these on his voyage and used them to support his theory of evolution.
What are fossils?
100
The formation of a new species.
What is speciation?
200
Organisms that can use sunlight energy or chemical energy to produce their own food.
What are autotrophs?
200
This is reduced when organisms are not fighting for the same resources in the same area at the same time.
What is competition?
200
Process by which organisms that are best suited for their environment survive and reproduce most successfully.
What is natural selection?
200
An organ such as the appendix that has little or no function in a modern organism, but used to work in an ancestor.
What is a vestigial structure?
200
Slow and steady evolution.
What is gradualism?
300
Temperature, sunlight, water, and soil are example of these factors.
What are abiotic factors?
300
A close relationship between two species where at least one species benefits.
What is symbiosis?
300
Traits that help an organism survive and reproduce better in its environment.
What are adaptations?
300
Two species have similarities in their embryo development indicating they share this.
What is a common ancestor?
300
Rapid evolution followed by a period of no change.
What is punctuated equilibrium?
400
Human activities that negatively impact the carbon cycle.
What are burning of fossil fuels or deforestation?
400
A fire destroys an area. Some seeds and small shrubs are left. Over time the area recovers.
What is secondary succession?
400
Unlike Darwin, Lamarck said that _________________ traits could be passed on to offspring.
What is acquired?
400
Similar bone structures as seen in the forelimbs of humans and the wings of birds that indicate an evolutionary relationship.
What are homologous structures?
400
Process by which a single species evolves into several different species that live in different environments.
What is adaptive radiation?
500
The 6 levels of organization in order from smallest to largest.
What are: individual, population, community, ecosystem, biome, and biosphere?
500
A volcano erupts destroying an area. Only bare rock is left. Lichens grow on the bare rock and over long periods of time, soil is formed, plants grow, and animals come to the area.
What is primary succession?
500
Scientific discovery that later proved Darwin's theory of evolution and disproved Lamarck's theory of acquired characteristics.
What is DNA?
500
A sequence of amino acids from cytochrome C is examined. A turtle and a monkey have 18 differences and a tuna and a turtle have 27 differences. This pair is the least related to each other.
Who is the tuna and the turtle?
500
Kind of evolution that accounts for unrelated species living in similar environments evolving structures with similar functions.
