Ecosystems
What is the definition of ecology?
The scientific study of interactions between organisms and their environments.
What is speciation?
When the gene pool of two populations are separated.
What is a convergent plate boundary?
Where two plates move towards each other
What material are fossils typically made of?
Stone
Which two spheres of the Earth did our first two units cover?
Biosphere and Geosphere/Lithosphere
What is a niche? What are the two types?
The unique role a species plays in it's environment. Realized and Fundamental
What type of speciation happens when two populations mate at different times or seasons?
Temporal

What are 3 types of fossilization?
Molds/Casts
Replacement
Permineralization
Carbonization
Tar/Ice
Trace
What are the 3 types of rock and how are they formed?
Sedimentary - weathering, erosion, pressure
Metamorphic - heat, pressure, chemical reaction
Igneous - intense heat
What is the difference between biotic and abiotic factors?
Biotic = living things
Abiotic = non-living things
When two species can no longer successfully reproduce and interbreed due to one living in mountains and one in the desert, and also have different exterior features, which two types of speciation does this represent?
Geographic and Mechanical
What evidence supports the theory of continental drift?
geographic fit, fossils match across continents, rock types, glacial patterns, tropical fossils in the antarctic, etc.
What are the three types of fossilization that preserve organic material?
Resin, tar, ice
What are the 3 main types of symbiosis? Give an example of each.
Mutualism - both benefit - clown fish and anemone
Commensalism - one benefits, one neutral - ramora and basking shark
Parasitism - ticks and deer
