The idea that organisms come from a common ancestor
What is a the evolution theory
100
Microevolution is the change in a population over time while MACROevolution is
What is the creation of new species and higher taxonomic groups
100
the succession in response to environmental disturbances that move a community away from its equilibrium
What is secondary succession
100
Can be exponential or logistic
What is survivor ship curves. Explain
100
Community of organisms and their enviroment
What is ecosystem
200
3 characteristics of evolution
What is characteristics are inherited, resources are limited (competition), and characteristics are varied
200
Divergent vs. Convergent evolution
What is divergent is a species that begins at a common point but evolves separately (flower) while convergent is when they are similar but are different species (bats and insects) and have no common ancestor
200
the number of different species in a community
What is species richness
200
the statistical study of changes in populations over time
What is demography
200
What leads to succession
What is disturbances
300
The best variation of a trait is the one that is passed down
What is natural selection
300
population genetics
What is looking at the frequency of alleles to see if a population is evolving
300
foundation species
What is a species which often forms the major structural portion of the habitat
300
the maximum number of individuals of a population that can be supported by the limited resources of a habitat
What is carrying capacity
300
Food Chain
What is a linear sequence of trophic (feeding) relationships of producers, primary consumers, and higher level consumers
400
Two ways variation can occur for genetic variation to take place
What is mutation and meiosis
400
Bottle neck effect
What is when a large portion of the population is killed
400
4 different defense mechanisms
What is mechanical, chemical, physical, behavioral
400
a species suited to stable environments that produce a few, relatively large offspring and provide parental care
What is K-selected species
400
Food web
What is a web of trophic (feeding) relationships among producers, primary consumers, and higher level consumers in an ecosystem
500
Matching of the organism to its enviroment
What is adaptation
500
Formation of new species
What is speciation
500
Competitive exclusion principle
What is the best obtain resources
500
a species whose presence is key to maintaining biodiversity in an ecosystem and to upholding an ecological community’s structure
What is keystone species
500
an increasing concentration of persistent, toxic substances in organisms at each trophic level, from the producers to the apex consumers
