(C P N) - C = predators search and attack probability P = number of predators N = number of prey (C P N) = consumption rate of prey Abiotic Factors - non-living chemical and physical factors (ex: temp, light, nutrient, water) Solutions are acclimation or adaptation amensalism - (- , 0) biotic factor; one species is negatively affected and the other remains unaffected (ex: big tree shades over smaller trees) Aristotle - wrote Historia Animalium Biotic factors - living factors aka other o...

3 mechanisms for prokaryot genetic recombination - 1.)Transformation 2.)Conjugation 3.)Transduction Absolute dating - -Radioactive isotopes decay over regular annual time periods (half-lives) -C14 5,700 yrs - radioactive isotopes vs stable isotopes -stable isotopes stay the same after the organism dies Alexander Fleming - -Discovered Penicillin -microbe v. microbe interaction -Capitalized on mistake in the lab, left plate out and fungus grew on it Algae - -Protist -plant like; photoau...

adaptative radiation - diversification of a group of organisms into forms filling different ecological niches allopatric speciation - aka geographical isolation: biological pops of the same species become isolated from each other to an extent that prevents or interferes with gene flow allopolyploidy - individual or strain whose chromosomes are composed of more than two genomes each of which has been derived more or less complete but possibly modified from one of two or more species -matin...

5 basic types of predation - carnivory, parasitism, parasitoids, cannabalism, herbivory Abiotic components - non-living chemical and physical factors(temperature, light, water, nutrients) ammensalism - one species is harmed and the other is unaffected(-,0) ex: larger tree shading smaller stature tree aquatic vs. terrestrial systems - terrestrial--> 3 trophic levels(odd number=resource limitation) aquatic--> 4 trophic levels(even number=consumer limitation) Aristotle - Historia anima...
