Question | Answer |
Coevolution | 2 species develop adaptations to increase the benefit of the relationship |
Population | all of one species in an area |
Density | number of individuals per unit area |
Dispersion | random(spread out), clumped, even |
Symbiosis | close relationship between two organisms |
Parasitism | one organism benefits, the other is harmed, usually not killed |
Commensulism | one organism benefits the other is unaffected |
Mutualism | both organisms benefit |
Predator / prey | example, predator kills prey |
Niche | roles and organism plays, includes home, interactions, and environmental factors |
Density independent deaths | deaths not effected by how close together organisms are, ex: weather related deaths |
Density dependent deaths | deaths effected by closeness of organisms, ex: disease |
Reproductive potential | maximum number of offspring a species produces, high potential=numbers increase rapidly, effected most by earlier reproductive age |
Exponential growth | population increases rapidly, ex: |
Carrying capacity | determined by most limited resources, maximum population an ecosystem can support |
Habitat | where an organism lives |
Competition | both organisms are harmed, does not occur between different ecosystems |
Generation time | average age at which a species reproduces |
Limiting resource | resource in lowest supply |
Niche restriction | using only part of available resources |
Population growth | birth rate minus death rate |
